IPv6 BGP Commands
IPv6 border gateway protocol (IPv6 BGP) is supported on the C-Series, E-Series, Z-Series and S4810 platforms.
BGP is an external gateway protocol that transmits interdomain routing information within and between Autonomous
Systems (AS). Basically, two routers (called neighbors or peers) exchange information including full routing tables and
periodically send messages to update those routing tables.

aggregate-address ipv6-address prefix-length [advertise-map
map-name] [as-set] [attribute-map map-name] [summary-only]
[suppress-map map-name]
Parameters
ipv6-address
