When a BGP session receives a unicast or multicast NLRI, it installs the route in the appropriate table (inet.0 or inet6.0 for unicast, and inet.2 or inet6.2 for multicast). To add unicast prefixes to both the unicast and multicast tables, you can configure BGP routing table groups. This is useful if you cannot perform multicast NLRI negotiation.
To configure BGP routing table groups, include the rib-group statement:
-
rib-group group-name;
For a list of hierarchy levels at which you can configure this statement, see the statement summary section for this statement.
