You start to send the Keepalive package and wait for the other party's The Protected port feature cannot be configured across switches: Access-list 1 permit 100.1.1.0 In a DHCP snooping environment (deployed on a switch), we consider ports as either trust or untrust , which is a trusted or untrusted interface. On the switch, configure the interface connected to the legal DHCP server as trust . Only received on the trust interface RIP-2 Only Ip arp inspection trust Path After 10.30.0 is passed to R3 , since the RIP updated subnet and the R3 interface subnet belong to the same main class network, R3 receives the update, and uses the interface mask as the mask of the RIP route, so the R3 routing table The route loaded in is: 10.1.20.0/24 Local origin R1 and R3 , R2, and R5 establish an EBGP neighbor relationship. Comparative principle So match interface is a match with the outbound interface attribute, and this ? 1 Neighbor 10.1.23.2 remote-as 200 Match ip address pref 1 set local-preference 200 RR self-originated route The following are five types of BGP packets and packet parsing: Experiment 3: Weighted extension Client-identifier unique-identifier *>i100.0.2.0/24 [Experiment 4 ] There is a main class network; there is a subnet route (match), the longest match Solution to provide more bandwidth The ETHERNET_SNAP standard was developed by the IEEE 802.1 committee to ensure interoperability between IEEE 802.3 LAN and Ethernet. SW2 is the core layer switch, deploying DHCP relay Active is 10.1.1.252 (primary), weighting 100 (expires in 7.028 sec) Arp replies sent: 1 1.0.0.0/8 route Y The next hop of 1.1.1.0/24 , because the AD value of OSPF is better than RIP . If R1 is configured as follows: Routing entry for 8.8.8.0/24 Le keyword is not written, then the default is greater than 24 less than 32 PVLAN considerations Advance The redistribute local route learned from the IGP routing protocol enters BGP , and the MED value inherits the metric in the IGP protocol. Focus on the configuration of GW : 10.1.13.3 After the basic BGP configuration is complete , R1 establishes an EBGP neighbor relationship with R3 , R2, and R5 . R3 establishes an IBGP neighbor relationship with R4 , R4, and R5 (using the LOOPBACK interface as the update source). The Permit/deny keyword has a different role in different deployment scenarios. Fa0/20 Start a TC while timer for the root port and all non-edge designated ports . The timer value is equal to 2 times the hello-time timer. If the outbound interface is a broadcast interface, it may impose an additional burden ( ARP ) on the nodes under the interface or cause potential problems. Router bgp 12 RouterB routing 100.100.100.0/24 passed to A , NEXT_HOP is 10.1.123.2 ; Now we consider that when R1 originates an OSPF internal route, both R2 and R3 can learn this route. Then on R2 , the route is re-released from process 1 to process 2 , and finally R3 will learn the route from R4 . So for R3 , the dual OSPF process, 100 i Sourced in sev-epoch 1 Encap length 14 Router bgp 11 When R2 Native vlan No off default route above configuration, adding a destined 13.0 network routing next hop is R3 , the PC to 13.0 data network switch to R3 proof ip default next-hop priority routing detail below, above Default route. The next hop (the Next Hop) - if present , it identifies a better than advertised router address of the next hop address. In other words , the next hop address it noted , that in the same measure than - advertised subnet router closer to the destination. If this field is set to all 0s (0.0.0.0), the address of the advertising router is the optimal next hop address. The mapped ethernet vlan will be blocked Address 10.1.12.1(10) Network 20.20.20.0 mask 255.255.255.0 Origin AS-Path Next hop access-list 1 deny 172.16.32.0 0.0.0.255 In fact, this is more a problem, because such an approach, in fact, the last 8 bit group no matter what, will be live match, he is even more imprecise.

Automatic summary EIGRP is run between R1 and R2 . At the same time, R1 and R2 announce their respective LOOPBACK interfaces in the EIGRP process. Source of routing information: How is this route learned, for example, static, or through OSPF , IS-IS , Based on UDP protocol ports 67 and 68 basic concept Dynamic routing protocol port number or protocol number If the interface is trunk , set the trunk protocol type In this way, the summary route inherits the detailed AS_PATH attribute, so atomic_aggregate is redundant. Therefore, in the above case, the generated summary route does not carry atomic_aggregate . Let's see: RIP and OSPF 5.5.5.5 ? Tables Access-list 1 permit 172.16.1.0 route-map unsupp permit 10 match ip address 11 Modify the AD value of EIGRP R1R2 establishes an IBGP neighbor relationship and maintains two BGP connections. The local interface is used to establish a neighbor relationship with the peer directly connected interface. BGP router identifier 10.1.13.3, local AS number 345 In 802.1D , the TYPE field uses only the highest and lowest bits to indicate TC and TC acknowledgment, and RSTP extends this field: BPDUguard CAM table Looking at the BGP table of R4 , we find that: We restore the experimental environment to the basic configuration: BGP neighbor relationships are as follows MED , choose 3 100 i This fulfills the demand. Metric Preferred routes sent by EBGP neighbors (relative to IBGP neighbors), preferred federated EBGP routes in federated EBGP and IBGP SW3 receives this BPDU , but finds that this BPDU is less preferred than its own locally stored BPDU , so the BPDU is ignored. Set ip next-hop 11.1.1.2 exit First of all, the route-map is a very important tool, and it is used in a wide range. When defining a route-map , we use the route-map keyword to associate a custom parameter, such as test . A route-map list by the test string unified representation, you may be in one route-map define a plurality of sequences, a sequence number to a decimal representation, such as the figure above, 10 , Route-map 55 If the route is marked d , it means that the route is suppressed. If it is h , it means that the route has signs of flipping. Deployment Highlights 63 Pointer to the target: The pointer does not point to the router's direct connection to the destination network or to another router address in the directly connected network , or to the local interface of the link. A router that is closer to the target network is called a next hop router.

The configuration of R3 is similar. 4.3.2 Message Type 35 A advertises the detailed route to B , B advertises the detailed route to C and D , and C advertises the summary route. At this time, the summary route will be transmitted to B in addition to being notified to D , and this may cause problems. Therefore, you need to filter the summary route on the IP distribution-list x of neighbor B on C. Otherwise, a routing loop will occur. ?

MTU? Refers to the second floor of the MTU , which is the interface MTU , refers does not contain a two-story frame header, Payload of MTU , the MTU value is generally not manually modify the default is 1500 bytes. Thus CISCO router supports Layer 2 data frame is a maximum value 1500 of payload plus the floor layer 2 frame header and the FCS : Objective MAC . 6 bytes + source MAC . 6 bytes + type field of 2 bytes + the FCS . 4 bytes So the total is 1518 bytes.
