Local 3.3.3.3 Internal 192.168.12.1 You can use show ip bgp regexp to check the results of the configured regular expression. FastEthernet1/0 Route filtering or execution strategy during redistribution Complete the basic interface IP configuration . Add the following configuration on R2 : / / used to define the condition prefix to be injected The standard ACL active part and destination part use the source matching route prefix and use the destination part matching route mask. The next outgoing interface of the route is the port of the match . ? Desirable: capita ask if the other side can/will FastEthernet1/0 5.5.5.5 1 : RIP-1 ; Router bgp 64512 CA004FEC0008CA014FEC00080800 ! If it is RIP , the network specified by the ip default-network command does not need to be displayed to announce RIP , and once the default gateway is specified,ccnp switch final exam answers, RIP Access-list 1 permit any route-map PBR permit 10 match ip address 1 // AS200 is the Primary AS and is used to configure the BGP process. Difficult to resolve And SW3 on the same case 3.3.3.3 When the topology changes, the spanning tree protocol can detect these changes and automatically adjust the interface status in time to adapt to network topology changes and achieve link redundancy. ACLs to release or discard ARP packets. Ip prefix-list huizong permit 172.16.0.0/16 ip prefix-list mingxi permit 172.16.1.0/24 ip prefix-list xiayitiao permit 10.1.24.4/32 route-map RP_mingxi permit 10 PAgP mode: Bgp connected eigrp 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. 7 Path Number of messages waiting to be sent to the neighbor in the outQ queue 8 2.2.2.2 Is 2 , 3 with AS the first comparison, 2 is MED small it is preferable; 2 with a further comparison, one of external routes it is preferably ( MED not compare) *> 100.0.1.0/24 Set interface specifies how to send such a packet set ip default next-hop specifies the next hop to be forwarded set ip next-hop specifies the next hop to forward Represents the upper layer protocol ( BPDU ), which is always 0. R2(config)#router ospf 1 Store all routing entries, as well as their properties. RFC1723 defines several compatibility switches Bgp dampening Switch(config-if)# ip address 192.168.255.254 255.255.255.0 At this time, R2ping 1.1.1.1 will pass (equivalent to 172.16.12.1 as the last hop help object) Use ip community-list to match the community value Configure the primary VLAN to associate the Layer 2 secondary VLAN to the primary VLAN. After the summary command is added with the as-set keyword, the generated summary route can inherit some path attributes of the detailed route, thus avoiding some problems. The rules for inheriting detail attributes from as-set are as follows: FastEthernet0/0 Ip dhcp snooping Configure BPDU is 0x00 and TCN BPDU is 0x80. To maintain a consistent BGP topology, the RR does not modify certain BGP path attributes when it reflects routes . These attributes include NH . Route-map BGP2OSPF permit 20 match ip address 2 In doing polymerization route, using as-set produced after AS-Path list {} in the AS length number only count a AS length number within the Union AS-Path list () in the AS number length Calculate basis The DAI is deployed on the switch to ensure that legitimate ARP requests or responses are released and illegal ARP messages are discarded. The main actions of the switch after deploying DAI are as follows: Ip address 3.3.3.3 255.255.255.0 * 10.1.25.2 R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. Port-channel interface cannot be the destination interface of SPAN In CISCO IOS , CEF can hash the source and destination IP addresses and import the hashed results into a load balancing table for load balancing. This table has 16 hash buckets , each of which points to an adjacency, and multiple buckets can point to an adjacency at the same time. You can use the show ip cef route prefix internal hidden command to see: ? By default, as long as DAI drops the message, it will be logged After the data transfer is completed, A to B transmits a data frame to tell B releasable attachment, the communication ends. R4 released the RIP route of 100.1.1.0/24 , which can be learned by both ASBRs . The solution is to configure static summary routes on the two ASBRs : You can learn these two external routes. BGP table on R7 : We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows A tool used to control routing updates can only filter routing information and cannot filter LSAs . Use CDP to detect next-hop IP reachability in PBR environment (without optional parameters) *> DAI - Dynamic ARP Inspection Bridge ID in the MAC , is the backplane of the switch MAC , the port ID in the MAC switch port MAC , all the view switch mac available Network 100.0.1.0 mask 255.255.255.0 Configure the SVI interface corresponding to the VLAN . Maximum route entry Neighbor R2 unsuppress-map test Next Hop We use ip ospf cost 100 on the F0/0 port of R4 to increase the interface cost , so the result is as follows: BGP routing table entry for 100.100.100.0/24, version 3 Paths: (2 available, best #1, table Default-IP-Routing-Table) Multipath: eBGP Interface fast0/1 200 2bb4c2a1 Same speed and duplex Clear ip bgp soft in // Inbound soft reset, locally send route-refresh to all BGP neighbors IP Start a TCP connection. Prepare enough resources when BGP is enabled If R1 turns off auto-summary and network 1.1.1.0 , the declaration is unsuccessful because there is no mask for class declaration. Metric Bgp confederation identifier 345 neighbor 4.4.4.4 remote-as 64512 neighbor 4.4.4.4 update-source Loopback0 UDP 10.1.13.1 Deployment points Reviewer Command ? ? Configuration command The routing between the internal LOOPBACK of the AS can be learned separately. Both R1 and R3 update the route of the 100 network segment to R2 . Without any policy, the BGP routing rule will always be compared to the RID , and finally the route of R1 is preferred . The configuration of R1 is as follows: Mismatch. This method requires that the community contains 100:11 and no-advertise to match. About IP Routing 5 / / Mark the routing table 192.168.1.0 as the default network A After receiving the response, you know B has established a connection with their locally. A also opens up an SAP value to indicate the connection, and sends a confirmation to B to establish the connection. At the same time, R4 also received the 100.0 route introduced by R2 , but it was not passed to R3 . This is the principle of horizontal splitting of IBGP : " BGP routers will not pass IBGP to him and pass it to other IBGP neighbors." The implementation of diversified strategies at the level has been able to achieve very good path control effects, and it is a very scientific and highly recommended method to control the flow of data by controlling routing. In addition to this, there are many, such as: Address Resolution Protocol Network 100.0.2.0 mask 255.255.255.0 Ip address 3.3.3.3 255.255.255.0 S0 192.168.12.1/24 r1 Redistributing Routing Protocols 40 Border Gateway Protocol (BGP) Connected Decision summary Route summary issues to be aware of Open Shortest Path First (OSPF) Routing Information Protocol (RIP) Route map reference R3 , R4 running the OSPF , the R3 on each can learn from the R1 and R2 of looback Load balancing mode 16 Set local-preference set weight AS does not compare the MED values. In other words, for multiple paths, the MED is compared only if the first AS in AS_SEQUENCE is the same ; any leading AS_CONFED_SEQUENCE will be ignored. MED only affects traffic between directly connected autonomous systems, and does not pass across ASs. 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 . Port-channel interface cannot be the destination interface of SPAN With the above configuration, the analog R3 received from AS200 and AS600 route, in case R3 on filter out from AS600 route, due AS600 route, the AS_PATH trailing end are 600 , so the regular expression can be used: _600 $ , Underscores are used to match spaces. Note, however, that the as-path access-list is also implicitly deny any by default , so be careful to deny the route from 600AS and leave the other routes.
