Next Hop !! wherein 2.2.2.2 is R2 of Router-ID , attention since 100.1.1.0 in R3 of OSPF Switchport access vlan 10 interface fast0/24 A default route will be published into the RIP and passed to other routers. For example, R1 , R2 , and R3 run RIP and open loopback on R1 . In the in direction, the distribution list can only filter the route when the LSA is received locally. When the route is generated, the router's own routing table that implements the distribution list will be affected by the distribution list (but the local LSDB still has the LSA ), and router will still LSADB in PS : In Ethernet, due to the conflict, two hosts on the shared medium send frames at the same time , which will cause conflicts. According to a specific algorithm, the minimum length of a frame in Ethernet is 64 bytes. Access port processing frame process Sw1(config-if-range)#no switchport // Configure the L3 interface * i100.0.1.0/24 Sh ip bgp neighbors {address} received-routes – LoopGuard and RootGuard cannot be enabled at the same time The default load balancing method is round-robin Decision making Locally find a route to the neighbor and try TCP three-way handshake. Waiting for completion, the authentication is completed during TCP setup. If the TCP connection is not up, enter the Active state and try to connect repeatedly. Used for unidirectional link detection, mainly for fiber links. Devices that need both ends of the link support UDLD Bgp default local-preference 500 // Modify the default lp value of the route originating locally Exist-map Sw1(config-if-range)#channel-group 1 mode desirable Sw1(config-if-range)#no shutdown Therefore, BGP automatically summarize ( Auto-the Summary ) Summary Only redistributed redistributed routes, and the use of network command routing incoming class declaration ways. Currently CISCO IOS turns off automatic summarization by default. By default, BGP does not allow static default routes to be injected when static is re-released ; unless it is in the BGP process at the same time default-information originate Burst interval , the default is 1s , optional configuration. This is a continuous detection period, used to detect the number of ARP packets in this time period . The default is 1S , so that is, within 1S , if 15 (default) ARP is exceeded , the violation is. This time can be selected from 1-15S. Client-identifier unique-identifier Activate the portfast feature for a specific interface Recognized as a self-determination attribute. LP is a local priority, only AS inside, in IBGP between peer transfer, and will not be passed to other EBGP neighbors Route-map OSPF3to1 permit 10 match tag 10 The summary of the route is actually done by the operation of the subnet mask. For the following example: 10.1.13.1 100 Run the switchport port-security mac-address command to configure a static security address entry. Note that although R4 passes the route 400 {100 , 200} , the AS in the braces is only calculated as an AS in the AS_PATH calculation. Therefore , the two EBGP routes received on R6 have the same AS_PATH length. Finally, R6 The route of the oldest EBGP neighbor will be preferred . R1 RIPv1 Convergence comparison between 802.1D and RSTP This command can be used in the following ways: Definition of 1042 . The most commonly used encapsulation format today is the format defined by RFC894 , commonly referred to as Ethernet II or Ethernet DIX . Infinite Ip dhcp snooping trust Forward ( If MED is empty , it is set to 0) Access-list 1 permit 192.168.1.0 route-map test permit 10 Port ID ( 2 bytes) = Port Priority (1 byte ) + Port ID (1 byte ) OR2 , SW1 , and SW2 run OSPF , and OR2 acts as the egress router of the telecommunications, injecting a default route into the OSPF domain. OR1 will be local The configuration of R2 is as follows: R5#show ip bgp 11.11.11.0 8 bits 201 200 ^(100|200)$ RFC1722 The bigger the priority Interface f0/1 Weight Neighbor 5.5.5.5 remote-as 345 Network 192.168.24.2 0.0.0.0 area 0 Once the port-channel interface is established, it forms a logical interface, and subsequent configuration of the interface is in the port-channel. On Demand stub Routes Switch(config)# interface fast0/15 If the route learns to a non- client IBGP peer , it is reflected to all clients and EBGP neighbors. After being injected into EIGRP , the tag is still carried. Interface loopback2 Matches the network number and prefix length in the route prefix to enhance the accuracy of the match. FastEthernet1/0 There are 2 forwarders (1 active) Non-default (manually configured non-default) priority and cost unchanged Load balancing methods R2 will use the primary address and the secondary address for validate-update-source , so R2 can learn 2.2.2.0 and 3.3.3.0 routes. Network Verify the role of the match interface 2 If R2 is added to the default route of R3 on the above basis, the data of the PC to the 10.1.13.0 network is still lost to R1 , which means that ip defaut-next-hop has higher priority than the default route. 100 Ip route-cache flow show ip cache flow Use the clear port-security configured command to clear all manually configured security address entries. Use the clear port-security all command to clear all security address entries. LocPrf Show ip dhcp binding Show dhcp binding on DHCP server Length : indicates the full length of the BGP packet, including the header. Blocking to forwarding state usually takes 30-50s (default 50S , ie 20+15+15 ), this time can also be adjusted by configuring the spanning tree timer. Path This is the ICMP redirect message sent by R1 to R3 . Note that the Gateway address field in the header is filled with the next hop IP that is closer to the destination than the destination . Core switch configuration: 1 Default seed metric Internet (well-known community) Remote-ID type Match community 11 exact-match // strict match : ccnp Path Network The configuration of R4 is as follows: Public If the packets of the same data stream are sent in different paths, the IP packets may need to be re-queued when they reach the destination. This may reduce the forwarding performance of traffic such as VoIP , or if the packets arrive out of order, the quality of service will be degraded, packets may be discarded, and delay jitter will be added. (2) By default, the routing entry of 1.0.0.0 updated by R1 is ignored. After configuring ip rip receive v 1 on S0, you can learn. Using route reflector 23 0 100 0 100 i *> 11.11.11.0/24 2011-12 The configuration is as follows: Debug dhcp detail External EIGRP Neighbor maximum-prefix xx Experiment continued, after the above configuration, R4 has passed BGP learned from the R1 two of BGP routes. Sw(config-if)#switchport mode private-vlan host Router bgp 345 Let's look at the picture and deploy a two-way re-release on R2 and R3 . Default-metric x Route-map usage scenario Represents a range. Matches only one of the characters contained in the range. The route to the LOOPBACK interface. Must be zero Request message: You can request the entire routing table or request specific routing information. Path VTP Operating Mode : Server Maximum VLANs supported locally 1005 FastEthernet1/0 That is to say, R5 goes to 100.0.1. and 2.0 each has two paths, which are through 10.1.25.2 and 3.3.3.3 , and finally R5. ... (maximum 25 ) The larger the Local_Pref , the higher the priority Redistribution will only perform re-release actions on routes in the routing table. When a data frame is sent from the Hybrid port, the switch determines whether the attribute of the VLAN on the port is Untag or Tag . If it is Untag , first strip the VLAN tag of the frame and then send it ; if it is a Tag , send the frame directly. Access-list 1 permit 192.168.1.0 0.0.0.255 Configure an interface as a passive interface: Origin IGP, metric 0, localpref 100, valid, internal, best Originator: 1.1.1.1, Cluster list: 2.2.2.2 802.1q By modifying the weight to influence the routing decision After the maximum number of allowed MAC addresses of the port-security interface is set , the security address entries associated with the interface can be obtained as follows: Passive-interface configuration The KEEPALIVE message contains only 19 bytes of BGP headers, and does not contain any other data. R3 and R4 , R4 and R5 establish IBGP neighbor relationships, and R3 R4 R5 uses LOOPBACK as the update source and refers to the neighbor . Complete the basic interface IP configuration . Add the following configuration on R2 : Aggregate-address 192.168.0.0 255.255.0.0 as-set advertise-map adv By default, BGP does not allow static default routes to be injected when static is re-released ; unless it is in the BGP process at the same time default-information originate For securing from the same AS body different routes advertised peer to be MED comparing command and bgp always-compare-med relationship is as follows: IP Address Device ID 100 Note that at this time, the routing table is used to recursively find the route to 10.1.12.2 , so there must be reachable routes in the routing table. The BGP update package is as follows. You can note that the length of the AS is 2 , which is " 300 , 100 ". Note that this is an ordered list of ASs . Can only be passed between IBGP peers (unless a policy is made, the LP value will not be lost between IBGP neighbors within the AS ), not in EBGP V1 defaults to send v1 to receive v1, v2 OSPF 's neighbor command is not the same as EIGRP . After testing, in the Ethernet environment, directly refer to the neighbor , and still send multicast hello.  open Below, let's look at an example: Route-map test permit 20 In R6 connecting the R4 interface to capture found update package 11.11.11.0 prefix attribute carried AS_PATH contains 2 th content: The role of the root bridge is preemptible Access permanent nontrunking mode and negotiate with the peer interface to make it a nontrunking link As a result, the directly connected network segments of all devices are also connected. In AS345 , the routes are also available. This is for BGP . We did not pay attention in OSPF declared the R3 's s0 / 0 and R5 is S0 / 0 interface. A non-reflector router can participate in IBGP full interconnection or as a reflector client. Switch(config-if)# ip address 192.168.10.254 255.255.255.0 <100-500> Community list number (expanded) expanded Add an expanded community-list entry Sw(config-if)#switchport private-vlan host-association 100 201 Too many neighbors, managing these IBGP adjacencies will be a challenge and burden the device. Fortunately, we have two measures to help solve the problem, 1 is the route reflector 2 is federated. Preference , will trigger Notifacation message , causing session interruption; but can use IN on AS border router Clear the dynamically learned security address entries on the interface. RootGuard Directional strategy.

If this number is exceeded, the router will close the BGP connection with the neighbor. Apply clear ip bgp Community-List. 11 the permit IP no-export (or no-export into NO-ADV ) You can not route the network , but the origin of the route, configure a summary static, and then network the summary route, this method is not recommended. ? As a result, the priority becomes the highest 4bits , which is why the priority must be a multiple of 4096 ( 2 to the power of 12 = 4096 ). In addition, the system ID , the value of the VLAN ID , such as the spanning tree of vlan10 , the bridge ID of the switch is " 4bits priority + 10 + switch MAC" 5.5.5.5 Knowledge review 200 i MED : 200 One way is to establish a fully interconnected IBGP Complete the basic interface IP configuration .
