Configuring BGP4+
46
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 router
To add the IPv6 address 2001:efff:89::23 of a neighbor in remote AS 1001 to the BGP4+ neighbor
table of a switch, enter the following command.
BigIron RX(config-bgp-ipv6u)# neighbor 2001:efff: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:efff:89::23) to the peer group peer_group1, enter
the following command at the BGP4+ unicast address family configuration level.
BigIron RX(config-bgp-ipv6u)# neighbor 2001:efff:89::23 peer-group peer_group1
Syntax: neighbor <ipv6-address> peer-group <peer-group-name>
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.
