AS200 cannot receive routes from other branch offices2. Branch Office 2 (AS300) cannot advertise its own routing information to other branch offices3. Branch Office 4 (AS500) cannot receive routing for branch Office 3 (AS400)Experimental address

Today, we gave a client a test report based on Route-map to filter through different routes to different end-to-end Cross-domain neighbors. The function point is very small, but for the junior students want to help. BGP is actually a very powerful routing protocol for routing filtering. CCIE is also the focus of the exam, in fact, there is a very good book to recommend to everyone: Hope to be useful to

1. If the next hop cannot be reached, do not consider2. Select a route with the maximum weight.3. If the route has the same weight, use the route with the highest local priority.4. If you have the same local priority, the BGP Route from the vrobgp is preferred.5. If there is

Experiment topology: R1 configuration: R2 configuration: R3 configuration: Verify: From the BGP general rule 1.1.1.0/24 's next hop should be R2 (123.1.1.2) but it has automatically changed to R1 123.1.1.1. This is the third party's next jump. This is a change in the control level. Route redirection is a change in the forwarding of the data plane, and the next hop does not change. (Refer t
