Configuring A Bgp Confederation - H3C S5500-EI series Operation Manual

Operation Manual – IPv4 Routing
H3C S5500-EI Series Ethernet Switches
Note:
In general, it is not required to make clients of a route reflector fully meshed. The
route reflector forwards routing information between clients. If clients are fully
meshed, you can disable route reflection between clients to reduce routing costs.
In general, a cluster has only one route reflector, and the router ID is used to identify
the cluster. You can configure multiple route reflectors to improve network stability.
In this case, you need to specify the same cluster ID for these route reflectors to
avoid routing loops.

5.7.5 Configuring a BGP Confederation

Follow these steps to configure a BGP confederation:
Enter system view
Enter BGP view
Configure a
BGP
confederation
Enable compatibility with routers
not compliant with RFC 3065 in the
confederation
Note:
A confederation contains 32 sub-ASs at most. The as-number of a sub-AS takes
effect in the confederation only.
If routers not compliant with RFC 3065 exist in the confederation, you can use the
confederation nonstandard command to make the local router compatible with
these routers.
To do...
Configure a
confederation ID
