Press the longest match, go this one IP routing troubleshootingNone LLC sublayer When ISP1 when down, and GW connected ISP1 interface not DOWN (such as closing ISP1 the CDP ), since the GW lost ISP1 of CDP The direct result of this command is that the metric of 192.168.12.0 in R3's original routing table is 30720 , but now it is 10000 , which becomes 40720 . We see that after the offset command is configured , what actually changes is the DLY that is updated to the neighbor . Because it is true that DLY is the best, the default Example 1 : When configuring the reflector, the client- to- client reflection is enabled by default, but if the client is fully interconnected, this command adds no to turn off the reflection between the clients. NEXT_HOP to 10.1.123.2 , then if C is not on the router to the IP of PVC , will be a problem, so this should be taken into account. ARP 1> Soft reset using updated routing information Route-map 55 LocPrf Add redundant routing 9 match. Such an approach will match community included 100: 11 routes. Supplementary explanation of the role of the as_set keyword: Path Control Overview If R1 turns off auto-summary and network 1.1.1.0 , the declaration is unsuccessful because there is no mask for class declaration. command Route-map test permit 10 Match tag 10 Tags Network xxx mask yyy route-map zzz Address-family ipv4 unicast ? 100 Port-channel interface cannot be the destination interface of SPAN Preferred routes sent by EBGP neighbors (relative to IBGP neighbors), preferred federated EBGP routes in federated EBGP and IBGP *end* TYPE Set ip next-hop 22.2.2.2 Ip route 0.0.0.0 0.0.0.0 null0 router bgp x Sw(config-vlan)#private-vlan association 201,202 Ip policy route-map x BGP router identifier 12.12.12.12, local AS number 64512 BGP table version is 2, main routing table version 2 [Case] ​​routing flipping * Run RIPv2 , the default R1 update 1.0.0.0/8 is summarized to R2 , and the automatic summary is closed on R1 , then R2 learns to 1.1.1.0/24 , and since it still starts automatic summarization, the update to R3 is 1.0.0.0. /8 . This time if R2 on ip route 1.1.1.0 255.255.255.0 null0 , then R2 is routed on the table 1.1.1.0 becomes static static routing,ccnp route 300-101 blog, and the R2 is no longer to R3 updated RIP 's Let's start with the above picture, starting from 172.16.0.0/16 . The next network number we see is 172.16.10.0/24 , which is obviously obtained after applying the VLSM variable length subnet mask. a 172.16.0.0/16 a master class this network subnet . So the so-called subnet, we can understand as a network number obtained by "stretching" the mask or borrowing from the host bit based on the default mask length of the category to which the network number belongs. In fact, 172.16.0.0/16 is an interval that includes 172.16.10.0/24 .
