Configuring BGP4+
46
To enable the BGP4+ switch to advertise the default route, enter the following command.
BigIron RX(config-bgp-ipv6u)# default-information-originate
Syntax: [no] default-information-originate
You can also enable the BGP4+ switch to send the default route to a particular neighbor by
specifying the neighbor <ipv6-address> 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+ switch to send the default route to a neighbor with the IPv6
address of 2001:efff:89::23, enter a command such as the following.
BigIron RX(config-bgp-ipv6u)# neighbor 2001:efff: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 switch 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 3ff0:ec21::/32 into the BGP4+ database, enter the following
command at the BGP4+ unicast address family configuration level.
BigIron RX(config-bgp-ipv6u)# network 3ff0:ec21::/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 switch to redistribute routes from the following sources into BGP4+:
• Static IPv6 routes.
• Directly connected IPv6 networks.
• IPv6 IS-IS.
