Because capabilities currently are negotiated only during session setup, capabilities
configured after the session are unavailable until the next session reset.
NOTE
Example 2-4 shows another example of BGP capabilities exchanged between a pair of
routers. Four capabilities are exchanged (advertised and received): route refresh (both old
and new forms), IPv4 Unicast, VPNv4 Unicast, and IPv4 Multicast. For each of the three
address families, more information is provided in its respective section.
