Advertising The Default Bgp4+ Route; Importing Routes Into Bgp4 - Dell PowerConnect B-RX Configuration Manual

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 peer-group <peer-group-name> parameter indicates the name of the already created peer
group.
To delete the mapping of the neighbor IPv6 address to the peer group, enter the no form of this
command.

Advertising the default BGP4+ route

By default, the BGP4+ switch does not originate and advertise a default BGP4+ route. A default
route is the IPv6 address :: and the route prefix 0; that is, ::/0.
You can enable the BGP4+ switch 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+ 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>]
