Configuring BGP4+
45
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> | <peer-group-name> 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
switch.
• Identify the neighbor interface over which the neighbor and local switch 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 AS 1000 to the
BGP4+ neighbor table of a switch, enter the following commands.
BigIron RX(config-bgp)# address-family ipv6 unicast
BigIron RX(config-bgp-ipv6u)# neighbor fe80:4398:ab30:45de::1 remote-as 1000
Syntax: neighbor <ipv6-address> remote-as <as-number>
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

it to do so by entering the neighbor <ipv6-address> | <peer-group-name> 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::/64. 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.
