Configuring BGP4+

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.
NOTE
Each address family configuration level allows you to access commands that apply to that particular
address family only. To enable a feature in a particular address family, you must specify any
associated commands for that feature in that particular address family. You cannot expect the
feature, which you may have configured in the BGP4 unicast address family, to work in the BGP4+
unicast address family unless it is explicitly configured in the BGP4+ unicast address family.
To exit from the IPv6 unicast address family configuration level, enter the following command.
BigIron RX(config-bgp-ipv6u)# exit-address-family
BigIron RX(config-bgp)#
Entering this command returns you to the global BGP configuration level.
Configuring BGP4+
Before enabling BGP4+ on a switch, you must enable the forwarding of IPv6 traffic on the switch
using the ipv6 unicast-routing command and enable IPv6 on at least one interface by configuring
an IPv6 address or explicitly enabling IPv6 on that interface.
NOTE
You are required to configure a router_id when running IPv6 only routing protocols.
To configure BGP4+, you must do the following:
•
•
The following configuration tasks are optional:

Enable BGP4+.
Configure BGP4+ neighbors using one of the following methods:
•
Add one neighbor at a time (neighbor uses global or site-local IPv6 address).
•
Add one neighbor at a time (neighbor uses a link-local IPv6 address).
•
Create a peer group and add neighbors individually.
Advertise the default route.
Import specified routes into BGP4+.
Redistribute prefixes into BGP4+.
Aggregate routes advertised to BGP4 neighbors.
Use route maps.
