Since the configuration of the first experiment Rl , therefore R2 Flights 13 segments, it is preferable that Rl , this time in R2 a clear click BGP neighbor Rl , and the Rl BGP connection DOWN , R2 Flights 13 routes and preferably the R3 , After R2 and R1 restore the BGP connection and receive the 13 route update of R1 again , R2 is still preferred to R3. Due to the existence of the principle of horizontal splitting, BGP requires that the IBGP be fully interconnected within the AS (here, the neighbor command specifies). (The root cause is in R2(config)# router eigrp 100 Match comprising 100 and 200 of AS_PATH Under normal circumstances,ccnp tshoot easy, the data is preferred to go ip next-hop , that is, go ISP2 Floating static route 23 Often used with the portfast feature on the interface for connecting to the host Switch Virtual Interfaces ( SVI ) DAI configuration policy About PBR By default, only one BGP process can be started on a single router and can belong to only one AS . DUAL AS allows us to run a secondary AS under the primary AS without terminal BGP connections , thus providing a mechanism for network migration. 100 BGP Deaggregation , also known as BGP splitting. Route summary We all know what the concept is. The advantage of route summarization is very obvious. It can reduce the entries of the routing table to optimize the network, but at the same time it also loses the accuracy of the route passed by the neighbor. For the detailed routing before the aggregation, we I don't know anything about it. Then split can be understood as a summary of the reverse action, when I receive a summary route, may be based on a purpose, I want to extract a specific detail route from the summary route, in order to strengthen the granularity of the route, of course The details are dependent on the summary route.
