Match a , a1 , 62 , 1b , xv2, etc. *> 11.11.11.0/24 Compare by default from top to bottom Host address. Metric Router ospf 1 Before routing 0bits must 0.0.0.0 ago 0 Ge bit match, in fact, all the bits does not matter, but also for the mask, that did not write ge keyword is implicit so ge 0 Le 32 , that is, cover The code length is greater than 0 and less than or equal to 32 . So this prefix list is permit (Update source verification failed), on the other hand, R2 will not receive the 1.1.1.0 route from R1 , and then pass the same interface, with 11.1.123.2 Exit Access-list 2 permit 192.168.2.0 0.0.0.255 route-map PBR permit 10 At the same time, R4 also received the 100.0 route introduced by R2 , but it was not passed to R3 . This is the principle of horizontal splitting of IBGP : " BGP routers will not pass IBGP to him and pass it to other IBGP neighbors." OSPF can let R3 learn 1.0/24 and 2.0/24 routes. 200 / / Configure etherchannel , ID is 1 , the mode is desirable 1,20,30 159 220 , 91 70 switchport trunk encapsulation dot1q switchport mode trunk FIG above, R1 to R2 update 1.1.1.0 , . 1 hop, when R1 DOWN off,ccnp troubleshooting forum, and R3 to R2 update 1.1.1.0 is . 5 hopping, R2 up to R1 route will vary with invalid timer expires becomes pdown State, then enter the timer of the holddown timer The switches at both ends of the trunk need to use the same trunk protocol. This strategy, we can also do on R3 , but the implementation direction of the strategy is in . Between routers, routing information is passed, and the distribution list has absolute control over routing information. 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.
