LOCAL-PREFERENCE The neighbor advertises the route. On R1 ,ccnp route 300-101 best book, filter out 11.11.11.0/24 routes, other release SW1#sh int trunk Followed by ACL to match traffic. When a BGP router sends a route update to its EBGP neighbor, it cannot carry the LP attribute. The LP value of the EBGP route received by the peer is empty. Abc+d Implementation points // There are routes in the routing table of R3 : 1.1.1.0 , 2.2.2.0 , 192.168.12.0 30.30.30.0/24 Beta VLAN isolated from each other, the broadcast can not cross VLAN communication, and therefore a different VLAN devices unable to reach between the general, different VLAN need to communicate with each other between the layer 3 device Other solutions, we will continue to introduce in the following experiments So in fact this is a macro command Match ip address prefix-list 1 route-map RP2 permit 10 In R1 to the 1.1.1.0 and 1.1.2.0 do a summary, as 1.0.0.0/8 , if coupled summary-only keyword, two details will be suppressed by inhibiting a bar if you want to cancel the details of a neighbor, Such as 1.1.1.0 , then Router bgp asnumber R2 re-advertises the A route, then according to the preemptive rule, R3 will ignore the R1 update about the A route. At the same time, due to the deployment of two-way re-release, R3 will further re-publish the learned A- route back to process 1 . The PVID is the "port default VLAN ID ", which means that a port belongs to the VLAN by default . Ip route 192.168.10.0 255.255.255.0 fast 0/0 Origin IGP, metric 0, localpref 100, valid, external, atomic-aggregate , best Port-Security violation penalties Another recommended solution is to adjust the management distance of the routing protocol: ( Well-known discretionary ) Router bgp 100 ? 100 Router ospf 100 After the configuration is complete, use clear ip bgp * soft to reset it softly. 50min is an absolute time, the countdown starts after the configuration is completed, and the countdown is always performed regardless of whether the MAC is still active. The ip community-list is also like ACL . There are standard and extension points, 1-99 is the standard, and 100-199 is the extension. Extended community-list Under normal circumstances, the data is preferred to go ip next-hop , that is, go ISP2 1.1.1.0 to 3.3.3.0 actually has two paths to go. If the RIP protocol is running in the network , in fact, for A , going to 3.3.3.0/24 can be shared by B and D load. However, in some cases, we hope to data is controlled, for example, we want to 1.1.1.0 Access 3.3.3.0 of the main traffic go B , when B hung up, then switch to the D on. So we simply in D deployment offset-List , in which the A notice 3.3.3.0 routing, increased 1 jump, then this route will be compared to B advertised to A route metric big a jump, A naturally preferably B .
