Remote-ID suboption fields ? When the number of prefixes received from the neighbor exceeds the maximum number 300 of 90% (default 75% ), generating a message log Match community 11 exact-match // strict match Set community no-advertise route-map setCommu permit 10 router bgp 300 Looking at the above picture, we made a manual route summary on R3 . This summary route was generated by R3 and passed to R4 . At this time, the AS_PATH of this summary route is 300 , and the detailed route under it is lost. AS_PATH attribute, then if R4 and R1 or Note that if you attempt this time SW2 on F0 / 2 interface priority piecemeal, and it is useless, because the port is looking at the sender ID . So if on SW1 , the port priority of F0/2 is reduced. Then on SW2 , F0/2 will win as the root port. Route metric is 0, traffic share count is 60 MED 100 i ( If MED is empty , it is set to 0) Then on R4 , you can only learn 1.1.1.0 . The OSPF metric on R4 going to 3.3.3.3 becomes 101 , which is larger than the metric going to 5.5.5.5 . Therefore, R4 goes to Both R1 and R2 are connected to the 2.2.2.0 network. At this time, R3 goes to ping 2.2.2.2 . Because the static route of the outgoing interface is used, R3 thinks that 2.2.2.0 is a locally connected network, so ARP request is sent , R1 , R2 , can receive the request message, and both respond to the request message (the premise two Neighbor 5.5.5.5 update-source Loopback0 / / used to match summary routes 1 IS-IS Finally: R4#sh ip b LEN : Number of bytes in the Agent Information field , excluding the length of the code and len fields "Double-point bidirectional" routing re-release is a simple model that can often be used in large networks. For example, in a financial network,ccnp route student guide, if a dynamic routing protocol is run between a secondary line and a branch router, then this model may be involved. The so-called two-point bidirectional refers to a node with two routes re-issued on the boundary of two routing domains, and the direction of re-distribution is bidirectional. For example, in the above figure, the secondary line has two aggregation routers for access to the following outlets or branch routers. Then the two routers are two-point. In addition, in order to make the routes of the entire network reachable, two-way routing re-distribution is deployed on the two routers, that is, OSPF is re-released to RIP , and RIP is also re-released to OSPF. .
