BGP4+ overview
The implementation of IPv6 supports multiprotocol BGP (MBGP) extensions that allow
Border Gateway Protocol version 4 plus (BGP4+) to distribute routing information.
BGP4+ supports all of the same features and functionality as IPv4 BGP (BGP4).
IPv6 MBGP enhancements include:
- An IPv6 unicast address family and network layer reachability information (NLRI)
- Next hop attributes that use IPv6 addresses
Note: The implementation of BGP4+ supports the advertising of routes among different address
families. However, it supports BGP4+ unicast routes only; it does not currently support
BGP4+ multicast routes.
Note: ICX 7150 devices do not support BGP4+.
