Configuring BGP4+
9
NOTE
The example above adds IPv6 neighbors at the BGP4+ unicast address family configuration level.
These neighbors, by default, are enabled to exchange BGP4+ unicast prefixes. However, if you add
IPv6 neighbors while at the global BGP configuration or IPv4 BGP unicast address family
configuration level, the neighbors will not exchange BGP4+ unicast prefixes until you explicitly
enable them to do so by entering the neighbor ipv6-address activate command at the BGP4+
unicast address family configuration level.
This section provides minimal information about adding BGP4+ neighbors, because its focus is to
provide information about configuring BGP4+.
Configuring BGP4+ neighbors using global or site-local IPv6 addresses
To configure BGP4+ neighbors using global or site-local IPv6 addresses, you must add the IPv6
address of a neighbor in a remote AS to the BGP4+ neighbor table of the local Virtual ADX device.
You must repeat this procedure for each neighbor that you want to add to a local device.
For example, to add the IPv6 address 2001:db8:f3e9:93e8:cc00::1 of a neighbor in remote AS
4500 to the BGP4+ neighbor table of a Virtual ADX device, enter the following commands:
Virtual ADX(config-bgp)# address-family ipv6 unicast
Virtual ADX(config-bgp-ipv6u)# neighbor 2001:db8:f3e9:93e8:cc00::1 remote-as 4500
Syntax: neighbor ipv6-address remote-as as-number
NOTE
The example above adds an IPv6 neighbor at the BGP4+ unicast address family configuration level.
This neighbor, by default, is enabled to exchange BGP4+ unicast prefixes. However, if you add an
IPv6 neighbor while at the global BGP configuration or IPv4 BGP unicast address family
configuration level, the neighbor will not exchange BGP4+ unicast prefixes until you explicitly enable
it to do so by entering the neighbor ipv6-address activate command at the BGP4+ unicast address
family configuration level.
The ipv6-address parameter specifies the IPv6 address of the neighbor. You must specify the
ipv6-address parameter in hexadecimal using 16-bit values between colons as documented in RFC
2373.
The as-number parameter indicates the number of the AS in which the neighbor resides.
To delete the neighbor from the BGP4+ neighbor table, enter the no form of this command.
Adding BGP4+ neighbors using link-local addresses
To configure BGP4+ neighbors that use link-local addresses, you must do the following:
• Add the IPv6 address of a neighbor in a remote AS to the BGP4+ neighbor table of the local
Virtual ADX device.
• Identify the neighbor interface over which the neighbor and local Virtual ADX device will
exchange prefixes.
• Configure a route map to set up a global next hop for packets destined for the neighbor.
