Address Family Configuration Level - Dell PowerConnect B-RX Configuration Manual

Configuring BGP4+
Brocade's 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. 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:
•
•
NOTE
Brocade's 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

Brocade's implementation of BGP4+ includes a new configuration level: address family. For IPv6,
Brocade currently supports the BGP4+ unicast address family configuration level only. (For IPv4,
Brocade supports the BGP4 unicast and BGP4 multicast address family configuration levels.) The
switch enters the BGP4+ unicast address family configuration level when you enter the following
command while at the global BGP configuration level.
BigIron RX(config-bgp)# address-family ipv6 unicast
BigIron RX(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.
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.
