On R2 and R3 , there are two OSPF processes. If shown, one is OSPF1 and the other is OSPF2 . Note that this dual process is mainly implemented on the two ASBRs R2 and R3 . Choose PAgP or LACP Router bgp 64513 no synchronization Neighbor 10.1.23.2 remote-as 201 // R3 means that the remote-as of R2 is 201 , which is the secondary AS. Used to announce aggregated and selected detail routes (suppress specific detail routes), followed by route-map xxx , matched by route-map !! wherein 2.2.2.2 is R2 of Router-ID , attention since 100.1.1.0 in R3 of OSPF * i MD5 digest : 0x49 0x3C 0x1F 0x79 0x15 0x00 0xC7 0xAE 0x0E 0xDC 0xDD 0xEF 0x93 0xA5 0xB6 0x26 Weight When the router performs a classless route lookup (by default,ccnp switch exam labs, ip classless ), it does not pay attention to the class of the destination address. It performs the longest match between the destination address and all known routes bit by bit . As you can see, the route carries the atomic-aggregate attribute, which is used to inform the downstream neighbor that this is the route attribute that summarizes the route and loses the detail. At the same time, the aggregator attribute identifies the summary location ( the RouterID of the AS and the summary router ). After receiving B , it judges whether its own resources are sufficient (that is, whether too many connections are established). If it is enough, it returns a confirmation message containing the SAP value identifying the connection .

Therefore, if it is in the direction, by deploying the distribution list, the specific route can be filtered, so that the local routing routing table of the distribution list is changed, and when the local router updates the routing information to the downstream router, the actually updated content is An entry that is affected by the distribution list.
