ccnp route v2

16/32 bit 0 ? // is equivalent to route-map not matching ( permit ) any entry, so all details are released The default priority is 32768, and the range is 0-65535 . The first 4 bits are the priority . The last 8 bits are used as the system id . The smaller the better , the multiple of 4096 . None This fulfills the demand. The summary of the route is actually done by the operation of the subnet mask. For the following example: This is a simple method of data offloading and path redundancy using the longest matching principle. Ip address 192.168.10.254 255.255.255.0 Path Ip address 100.0.1.1 255.255.255.0 2 : Reponse message,ccnp route v2, send all or part of its routing information, in a Response message The configuration of R2 is as follows: Pipe character, logical or Site-level site identification: Identify the various sites on the network at the data link layer. [123].[7-9] Sender ( R2 ) saves basic configuration, such as BGP neighbor relationships Match ip address prefix-list 1 2 192.1.168.3 3 0003.44d6.c52f 2BB648EB interface-id 1bdb223f Policy-list is only supported in BGP . Other IP routing protocols do not support this feature. At this time, R1 is preferred . If you want R2 to be preferred R3 ? R2 is added as follows: In AS inside, due to the presence IBGP split horizon, making BGProuter had twenty-two established between IBGP connection, in order to get the full BGP routing updates, but this is a very low scalability approach, but also brought to the network device The two effective ways to solve the IBGP scalability problem are route reflectors and federation. Compared with the federation, the route reflector has the advantage that all routers in the federation need to support and understand the federated mechanism. The route reflector only needs the RR to understand the reflector mechanism. In addition, the implementation mechanism of the route reflector is relatively simple. Of course, if you want to manage large-scale AS with various EBGP mechanisms , then the federation will be a better solution.
