Points for Attention in BGP Route Convergence

Publication Date:  2012-07-27 Views:  35 Downloads:  0
Issue Description
If ASBR contains equipment from both Huawei and C company, all traffic will be routed to Huawei product if the routing is on the basis of AS_SET.
Alarm Information
Null
Handling Process
For the routing of converged route, the BGP routing depends on non-AS hop. 
Root Cause
During the convergence of BGP routes, add the aggregation item for the route converged, or add AS_SET to the converged route. 
AS_SET is the disordered set of AS_Path of all specific routes in convergence. 
VRPv5 is one AS hop for one AS_SET. However, the IOS of C company takes the AS number in AS_SET as one hop. 
Suggestions
Null
