Brocade FastIron Ethernet Switch Layer 3 Routing Configuration Guide - Manual (Page 532)

You can enable the BGP4+ device to advertise the default BGP4+ route by specifying the default-
information-originate command at the BGP4+ unicast address family configuration level. Before
entering this command, the default route ::/0 must be present in the IPv6 route table.
To enable the BGP4+ device to advertise the default route, enter the following command:
device(config-bgp-ipv6u)# default-information-originate
Syntax: [no] default-information-originate
You can also enable the BGP4+ device to send the default route to a particular neighbor by specifying
the neighbor default-originate command at the BGP4+ unicast address family configuration level.
This command does not require the presence of the default route ::/0 in the IPv6 route table.
For example, to enable the BGP4+ device to send the default route to a neighbor with the IPv6
address of 2001:db8:89::23, enter a command such as the following:
device(config-bgp-ipv6u)# neighbor 2001:db8:89::23 default-originate
Syntax: [no] neighbor ipv6-address default-originate [ route-map name ]
The ipv6-address parameter specifies a neighbor by its IPv6 address. You must specify this address in
hexadecimal using 16-bit values between colons as documented in RFC 2373.
Specifying the optional route-map name parameter injects the default route conditionally, based on
the match conditions in the route map.
Importing routes into BGP4+
By default, the device does not import routes into BGP4+. This section explains how to use the
network command to enable the importing of specified routes into BGP4+.
NOTE
The routes imported into BGP4+ must first exist in the IPv6 unicast route table.
For example, to import the IPv6 prefix 2001:db8::/32 into the BGP4+ database, enter the following
command at the BGP4+ unicast address family configuration level:
device(config-bgp-ipv6u)# network 2001:db8::/32
Syntax: network ipv6-prefix/prefix-length [ route-map name ]
You must specify the ipv6-prefix parameter in hexadecimal using 16-bit values between colons as
documented in RFC 2373.
You must specify the prefix-length parameter as a decimal value. A slash mark (/) must follow the
ipv6-prefix parameter and precede the prefix-length parameter.
You can specify the optional route-map name parameter if you want to change attributes of a route
when importing it into BGP4+.
To disable the importing of a specified route, enter the no form of this command without the route-map
parameter.
Redistributing prefixes into BGP4+
You can configure the device to redistribute routes from the following sources into BGP4+:
