Configuring BGP4+

46

Create a peer group and add neighbors individually.

The following configuration tasks are optional:

Advertise the default route.

Import specified routes into BGP4+.

Redistribute prefixes into BGP4+.

Aggregate routes advertised to BGP4 neighbors.

Use route maps.

Enabling BGP4+

To enable BGP4+, enter commands such as the following.

BigIron RX(config)# router bgp

BGP: Please configure 'local-as' parameter in order to run BGP4.

BigIron RX(config-bgp)# local-as 1000

These commands enables the BGP4+ switch and configure the autonomous system (1000) in
which your switch resides.

Syntax: [no] router bgp

To disable BGP, enter the no form of this command.

Syntax: local-as <number>

Specify the AS number in which the switch you are configuring resides.

After enabling BGP4+, you can add neighbors to a BGP4+ switch by entering a commands such as
the following.

BigIron RX(config-bgp)# address-family ipv6 unicast

BigIron RX(config-bgp-ipv6u)# neighbor 2001:4383:e0ff:783a::4 remote-as 1001

BigIron RX(config-bgp-ipv6u)# neighbor 2001:4383:e0ff:783a::5 remote-as 1001

These commands add two neighbors with global IPv6 addresses 2001:4383:e0ff:783a::4 and
2001:4383:e0ff:783a::5 in AS 1001.

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> | <peer-group-name> 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+. For more information about the parameters you can
use with this command, refer to the Router Configuration Guide.
