IPv6 BGP Commands
IPv6 border gateway protocol (IPv6 BGP) is an external gateway protocol that transmits interdomain routing information with extended IP
address space 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.
