Configuring BGP4+

Identifying a neighbor interface
To specify Ethernet interface 3/1 as the neighbor interface over which the neighbor and local
switch will exchange prefixes, enter the following command.
BigIron RX(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::/64. 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 switch 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).
BigIron RX(config-bgp-ipv6u)# neighbor fe80:4398:ab30:45de::1 route-map out
next-hop
BigIron RX(config-bgp-ipv6u)# exit
BigIron RX(config)# route-map next-hop permit 10
BigIron RX(config-route-map)# match ipv6 address prefix-list next-hop-ipv6
BigIron RX(config-route-map)# set ipv6 next-hop 2011:e0ff:3764::34
This route map applies to the BGP4+ unicast address family under which the neighbor route-map
command is entered. This route map applies to the outgoing routes on the neighbor with the IPv6
link-local address fe80:4393:ab30:45de::1. If an outgoing route on the neighbor matches the
route map, the route is distributed through the next hop switch with the global IPv6 address
2011:e0ff:3764::34.
Syntax: neighbor <ipv6-address> route-map [in | out] <name>
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 in keyword applies the route map to incoming routes. The out keyword applies the route map to
outgoing routes.
The <name> parameter specifies a route map name.
Syntax: route-map <name> deny | permit <sequence-number>
The name parameter specifies a route map name.
The deny keyword denies the distribution of routes that match the route map. The permit keyword
permits the distribution of routes that match the route map.
The <sequence-number> parameter specifies a sequence number for the route map statement.
