100 R4 and R2 , we look R2 , R2 moment from R4 has learned this RIP routes, if it from the R3 also learn the route and of the route metric is smaller, then, R2 will preferably from R3 this Routes , so that R1 , R2 , and R3 form a routing loop. The optional parameter length is used to indicate the length of the optional parameter field For details on the related fields of the BGP table, see the show section of the BGP Configuration section of this document. Sw1(config)#interface range fastEthernet 0/1 – 2 Ip route 172.16.3.0 255.255.255.0 172.16.12.3 Summarizing on R3 suppresses all details, but if you only want to release partial details for a particular neighbor, you can use unsuppress-map Assigning community 100:11 to route 11.11.11.0/24 on R1 and passing it to R2 , then R1 is configured as follows: Once the portfast port is connected to the device, the interface can bypass the listening and learning states and enter the forwarding state directly . Penalty value: 1000 per swing Paths: (1 available, best #1, table Default-IP-Routing-Table) Not advertised to any peer R1 , R2 , and R3 run RIP , and 1.1.1.0/24 on R1 is not directly announced. On R2 : Update timer update timer 13 If you configure the following, then the COST comparison will exceed the weight and become the most preferred comparison rule. 10.1.13.1 4 3 O IA C Bgp bestpath med confed R3#show ip bgp Fa0/20 Redirect time 600 sec, forwarder time-out 14400 sec Preemption disabled Route summary 23 Store all routing entries, as well as their properties. Ip route 100.0.0.0 255.0.0.0 null0 Multicast capability LocPrf 1.1.1.1 For example, R1 redistributed into direct on the OSPF , with out distribution list can be filtered out direction 1.1.1.0 this external routes. But R1 redistributed incoming routing, if R2 with the out distribution lists direction tried to block R3 accepted routes or LSA , you can not, because this is not a local external routes originating. 1-4094 5.5.5.5 ? Enables multiple gateways to be used at the same time and automatically detects active gateways. ! // match AS (100,2 ) and ( 200,2 ) When ISP1 is down,ccnp switch or router first, and the interface of GW connected to ISP1 is DOWN , the data of PC accessing 100 network is switched to ISP2. RIP re-advertises routes to OSPF : 200 10.1.12.1 from 10.1.12.1 (1.1.1.1) [Experiment 1 ] The following are several situations. The configuration of R4 is as follows: The configuration of R2 is as follows: Detailed rules The introduction of Cluster is to provide redundancy in the environment of RR . In conventional clustering design, a plurality of RR is used for one or more client service, these RR are configured the same CLUSTER_IDs , the ID is the 4 -byte IP form identifier default is RR own BGProuterID If two RRs have the same CLUSTER_ID , then they belong to the same cluster. Another very important role of CLUSTER_ID is anti-ring. When a RR receives BGP routing updates, it carries the same ROUTERID as its own .
