BGP routing rules * i100.0.2.0/24 After receiving this poisoning message, B erases 10.4.0.0 from the routing table, but it still exists in the rip database , the status is possible down , the garbage collection time ( Garbage colletion CISCO default 60S ), the route is from B. The database is erased. Complete the basic interface IP configuration . Add the following configuration on R2 : Mismatch. This method requires that the community contains 100:11 and no-advertise to match. Match ip address prefix-list 1 set as-path prepend 100 route-map test permit 20 ? BGP routing rules 1 Set tag 20 Solution: Use distribution lists to circumvent suboptimal path problems 101 AS_CONFED_SEQUENCE A list of ordered AS numbers on a path to a particular destination. When the network is normal, the data is forced to go ISP1 , ping 100 remote network data to ISP1 Local Advertised to update-groups: 1 BGP routing table entry for 172.16.0.0/16, version 4 The out- direction policy cannot be used separately for the member of the peer-group . It can only be used for the entire group . The in direction does not have this restriction. All neighbors in the same peer group must be all iBGP neighbors or all eBGP neighbors. 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. Can affect BGP routing (before the equivalent load balancing), somewhat similar to " tie breaker " in the path selection, is to break the tangles when tangled R* 0.0.0.0/0 [120/1] via 192.168.12.1,ccnp route official cert guide pdf, 00:00:03, Serial0/0 RouterID : 172.16.8.1 Ip community-list 1 permit no-export ip community-list 1 permit 12:1111 Vlan 100 The configuration of R1 is as follows: Set the interface to access mode In SW3 created on 10 , 20 , 30 three VLAN ! In the nogotiate permanent link aggregation mode, the neighbor must be manually configured as a trunk gate and no DTP frame is sent . Generally used when the peer device does not support DTP .

Looking at the figure above, we redistribute OSPF routes into RIP on R2 . As mentioned above, when re-publishing, you can use the metric keyword to set the metric after the route is re-advertised into RIP . Set to 1 here . The immediate result is that all OSPF routes injected into RIP have a metric of 1 . So what if I want to make some flexibility adjustments? For example, I hope that after the route is injected into RIP , the metric of the 192.168.1.0 route is 1 and the metric of 2.0 is 2 . Traditional redistribution is impossible.
