Configuring BGP4+

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 Virtual ADX device, enter the following commands:
Virtual ADX(config-bgp)# address-family ipv6 unicast
Virtual ADX(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 ipv6-address ctivate 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.
Identifying a neighbor interface
To specify Ethernet interface 3/1 as the neighbor interface over which the neighbor and local
Virtual ADX device will exchange prefixes, enter the following command:
Virtual ADX(config-bgp)# neighbor fe80:4398:ab30:45de::1 update-source ethernet
3/1
Syntax: neighbor ipv6-address update-source ipv4-address | ethernet port | loopback number |
ve number
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 ipv4-address parameter specifies the IPv4 address of the update source.
The ethernet | loopback | ve parameter specifies the neighbor interface over which the neighbor
and local Virtual ADX device will exchange prefixes. If you specify an Ethernet interface, also specify
the port number associated with the interface. If you specify a loopback or VE interface, also
specify the loopback or VE number.
Configuring a route map
To configure a route map that filters routes advertised to a neighbor or sets up a global next hop for
packets destined for the neighbor with the IPv6 link-local address fe80:4393:ab30:45de::1, enter
commands such as the following (start at the BGP4+ unicast address family configuration level):
