Configuring BGP4+
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:
Brocade(config-bgp-ipv6u)# exit-address-family
Brocade(config-bgp)#
Entering this command returns you to the global BGP configuration level.
Configuring BGP4+
Before enabling BGP4+ on a device, you must enable the forwarding of IPv6 traffic on the device
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.
To configure BGP4+, you must do the following:
• Enable BGP4+.
• Configure BGP4+ neighbors using one of the following methods:
• Add one neighbor at a time (neighbor uses global or unique local IPv6 address).
• Add one neighbor at a time (neighbor uses a link-local IPv6 address).
• Create a peer group and add neighbors individually.
The following configuration tasks are optional:
• Advertise the default route.
• Import specified routes into BGP4+.
• Redistribute prefixes into BGP4+.
• Aggregate routes advertised to BGP4 neighbors.
• Use route maps.
Enabling BGP4+
To enable BGP4+, enter commands such as the following:
Brocade(config)# router bgp
BGP: Please configure 'local-as' parameter in order to run BGP4.
Brocade(config-bgp)# local-as 1000
These commands enables BGP4+ and configures the autonomous system (1000) in which your
device resides.
Syntax: [no] router bgp
To disable BGP, enter the no form of this command.
Syntax: local-as number
