Address family configuration level
The implementation of IPv6 supports multi protocol BGP (MBGP) extensions, which allow IPv6 BGP
(known as BGP4+) to distribute routing information for protocols such as IPv4 BGP. The supported
protocols are identified by address families. (For information about address families, refer to
“Address family configuration level” on page 514.) The extensions allow a set of BGP4+ peers to
exchange routing information for multiple address families and sub-address families.
IPv6 MBGP functions similarly to IPv4 MBGP except for the following enhancements:
• 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.
Address family configuration level
The implementation of BGP4+ includes a new configuration level: address family. For IPv6,
Brocade devices currently support the BGP4+ multicast and unicast address family configuration
levels. The device enters the BGP4+ unicast address family configuration level when you enter the
following command while at the global BGP configuration level:
Brocade(config-bgp)# address-family ipv6 unicast
Brocade(config-bgp-ipv6u)#
The (config-bgp-ipv6u)# prompt indicates that you are at the BGP4+ unicast address family
configuration level.
While at the BGP4+ unicast address family configuration level, you can access several commands
that allow you to configure BGP4+ unicast routes. The commands that you enter at this level apply
only to IPv6 unicast address family only. You can generate a configuration for BGP4+ unicast routes
that is separate and distinct from configurations for IPv4 unicast routes and IPv4 BGP multicast
routes.
NOTE
The commands that you can access while at the IPv6 unicast address family configuration level are
also available at the IPv4 unicast and multicast address family configuration levels. Where relevant,
this section discusses and provides IPv6-unicast-specific examples. You must first configure IPv6
unicast-routing in order for any IPv6 routing protocol to be active.
