Traditional BGP-4 can only manage IPv4 unicast routing information. In order to provide support for multiple network layer protocols, MP-BGP extends BGP-4. Among them, MP-BGP's support for IPv6 unicast networks is called BGP4+, and BGP4+ carries routing next-hop address information through the NextHop attribute.
