Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 527)

For more information on performing these configuration tasks, refer to FastIron Ethernet Switch
Administration Guide.
To configure BGP4+, you must do the following:
• Enable BGP4+.
• Configure BGP4+ neighbors using one of the following methods:
‐ Add one neighbor at a time (neighbor uses global or site-local IPv6 address).
‐ Add one neighbor at a time (neighbor uses a link-local IPv6 address).
‐ 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:
device(config)# router bgp
BGP: Please configure 'local-as' parameter in order to run BGP4.
device(config-bgp-router)# local-as 1000
These commands enable BGP4+ and configure the autonomous system (1000) in which your device
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 device you are configuring resides.
After enabling BGP4+, you can add neighbors to a BGP4+ device by entering commands such as the
following:
device(config-bgp-router)# address-family ipv6 unicast
device(config-bgp-ipv6u)# neighbor 2001:db8:e0ff:783a::4 remote-as 1001
device(config-bgp-ipv6u)# neighbor 2001:db8:e0ff:783a::5 remote-as 1001
These commands add two neighbors with global IPv6 addresses 2001:db8:e0ff:783a::4 and
2001:db8: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 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+.
