Configuring BGP4+ neighbors using global or site-local IPv6
addresses
To configure BGP4+ neighbors using global or link-local IPv6 addresses, you must add the IPv6
address of a neighbor in a remote autonomous system to the BGP4+ neighbor table of the local
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:db8:93e8:cc00::1 of a neighbor in remote AS 4500 to the
BGP4+ neighbor table of a device, enter commands such as the following:
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor 2001:db8:93e8:cc00::1 remote-as 4500
Syntax: neighbor ipv6-address remote-as as-number
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 autonomous system to the BGP4+ neighbor table
of the local device.
• Identify the neighbor interface over which the neighbor and local device will exchange prefixes.
• Configure a route map to set up a global next hop for packets destined for the neighbor.
Adding BGP4+ neighbor
To add the IPv6 link-local address fe80:4398:ab30:45de::1 of a neighbor in remote autonomous
system 1000 to the BGP4+ neighbor table of a device, enter the following commands:
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor fe80:4398:ab30:45de::1 remote-as 1000
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 activate command at the BGP4+ unicast address family configuration level.
The ipv6-address parameter specifies the IPv6 link-local address of the neighbor. A link-local address
has a fixed prefix of FE80::/10. 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.
