Configuring MBGP

28

NOTE

If the BigIron RX has multiple neighbors with similar attributes, you can simplify configuration by
configuring a peer group, then adding individual neighbors to it. The configuration steps are similar,
except you specify a peer group name instead of a neighbor IP address when configuring the
neighbor parameters, then add individual neighbors to the peer group.

The command is the same as the command for configuring a unicast BGP neighbor, except in
MBGP, the command is entered in the IPv4 multicast address family level. Here is the full syntax
for the neighbor command.

Syntax: [no] neighbor <ip-addr> | <peer-group-name>

[advertisement-interval <num>]
[default-originate [route-map <map-name>]]
[description <string>]
[distribute-list in | out <num,num,...> | <acl-num> in | out]
[ebgp-multihop [<num>]]
[filter-list in | out <num,num,...> | <acl-num> in | out | weight]
[maximum-prefix <num> [<threshold>] [teardown]]
[next-hop-self]
[password [0 | 1] <string>]
[prefix-list <string> in | out]
[remote-as <as-number>]
[remove-private-as]
[route-map in | out <map-name>]
[route-reflector-client]
[send-community]
[soft-reconfiguration inbound]
[shutdown]
[timers keep-alive <num> hold-time <num>]
[update-source loopback <num>]
[weight <num>]

The <ip-addr> | <peer-group-name> parameter indicates whether you are configuring an individual
neighbor or a peer group. If you specify a neighbor’s IP address, you are configuring that individual
neighbor. If you specify a peer group name, you are configuring a peer group.

The remote-as <as-number> parameter specifies the AS the MBGP neighbor is in. The
<as-number> can be a number from 1 – 65535. There is no default.

NOTE

The BigIron RX attempts to establish a BGP4 session with a neighbor as soon as you enter a
command specifying the neighbor’s IP address. If you want to completely configure the neighbor
parameters before the device establishes a session with the neighbor, you can administratively shut
down the neighbor.

Optional configuration tasks

The following sections describe how to perform some optional BGP4 configuration tasks.
