In the IGP era, we all know, for example, OSPF, link state protocol, in the routing of the time, than the cost of the link, which link consumption will be more priority, if two of the same link consumption, then do load balancing. In fact, the 2 principles to achieve the OSPF---shortest path first work principle. What if, in BGP, there are multiple routes to achieve the goal, how should the choice be made? Which path is the preferred one? Take a lo

Some experiences in man will be shared with you. The approximate topology is shown in (physical connection diagram). The two downlink devices (R1 and R2) and the two core devices both establish IBGP neighbor relationships with the two route reflectors RR, in the BGP of R1 and R2, use the network to publish the network segment 192.168.1.0/24 at the same time. 1.

synchronization can continue layer-3 packet forwarding when the RP and the centralized route table are switched. What is Cisco IOS installed on the above router platform? Software 12.0 (22) S or later can support Cisco NSF. It can shorten the router downtime when the primary RP is scheduled for maintenance or when the RP encounters an unexpected fault. In most c

Note: PBR was previously a major tool used by Cisco to discard messages. For example, set interface null 0, which, according to Cisco, would save a bit more overhead than the ACL's deny. Here I remind: Interface NULL 0No IP unreachable//Join this commandThis avoids the return of many ICMP unreachable messages because of the large number of packets discarded. When a three-tier device forwards a packet base

(i) Route Maps Characteristics: The Route maps is similar to access lists, except that Route maps can change some of the properties of the packets/routes. Use: Route maps is mainly used for redistribution and Policy Routing and BGP implementation. Realize: Policy routi

For example, we only want r3 to learn 1.1.1.1 and 2.2.2.2. The steps are as follows: Write aclR2 (
