Associating a Route Reflector with a Cluster ID
In an AS with multiple clusters of route reflectors, you assign a cluster ID to each
cluster and associate each route reflector with a cluster.
For information about the IBGP route reflector, see “Configuring IBGP as a Route
Reflector or an RR Client” on page 8-77.
Disabling and Reenabling Route Aggregation
By default, BGP aggregates non-BGP-originated subnet routes to their
corresponding natural network routes for advertisement to BGP peers.
You can use the BCC to disable this feature. (This switch does not affect the
advertisement of BGP-originated routes.)
Navigate to the BGP prompt and enter:
subnet-aggregation
state
state is one of the following:
enabled
(default)
disabled
For example, the following BCC command disables subnet aggregation:
/jointfilesconvert/92449/bgp# subnet-aggregation disabled
/jointfilesconvert/92449/bgp#
