Configuring BGP4+
9
To exit from the IPv6 unicast address family configuration level, enter the following command:
Virtual ADX(config-bgp-ipv6u)# exit-address-family
Virtual ADX(config-bgp)#
Entering this command returns you to the global BGP configuration level.
Configuring BGP4+
Before enabling BGP4+ on a Virtual ADX device, you must 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 site-local IPv6 address).
• Add one neighbor at a time (neighbor uses a link-local IPv6 address).
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:
Virtual ADX(config)# router bgp
BGP: Please configure 'local-as' parameter in order to run BGP4.
Virtual ADX(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
Specify the AS number in which the device you are configuring resides.
After enabling BGP4+, you can add neighbors to a BGP4+ device by entering a commands such as
the following:
Virtual ADX(config-bgp)# address-family ipv6 unicast
Virtual ADX(config-bgp-ipv6u)# neighbor 2001:db8:4383:e0ff:783a::4 remote-as 1001
Virtual ADX(config-bgp-ipv6u)# neighbor 2001:db8:4383:e0ff:783a::5 remote-as 1001
These commands add two neighbors with global IPv6 addresses 2001:db8:4383:e0ff:783a::4 and
2001:db8:4383:e0ff:783a::5 in AS 1001.
