Configuring BGP4+

NOTE

You can add IPv6 neighbors only to an IPv6 peer group. You cannot add an IPv4 neighbor to an IPv6
peer group and vice versa. IPv6 and IPv6 peer groups must remain separate.

To configure a BGP4+ peer group, you must perform the tasks listed below.

1. Create a peer group.

2. Add a neighbor to the local device.

3. Assign the IPv6 neighbor to the peer group.

4. Activate the IPv6 neighbor and peer group.

Creating a BGP4+ peer group

To create a peer group named “peer_group1,” enter the following commands:

Brocade(config-bgp)# address-family ipv6 unicast

Brocade(config-bgp-ipv6u)# neighbor peer_group1 peer-group

Syntax: neighbor peer-group-name peer-group

Specify a name for the peer group.

To delete the peer group, enter the no form of this command.

Adding a neighbor to a local device

To add the IPv6 address 2001:db8:89::23 of a neighbor in remote AS 1001 to the BGP4+ neighbor
table of a device, enter the following command:

Brocade(config-bgp-ipv6u)# neighbor 2001:db8:89::23 remote-as 1001

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 | peer-group-name activate command at the
BGP4+ unicast address family configuration level.

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.

Assigning IPv6 neighbor to peer group

To assign an already configured neighbor (2001:db8:89::23) to the peer group peer_group1, enter
the following command at the BGP4+ unicast address family configuration level:
