Configuring MBGP
Syntax: [no] neighbor <ip-addr> | <peer-group-name>
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 BigIron RX 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.
NOTE
This section shows some of the more common optional tasks, including all the tasks that require
you to specify that they are for MBGP. Most tasks are configured only for BGP4 but apply both to
BGP4 and MBGP. For information on these other tasks, refer to
and
Advertising routes from the local AS to MBGP
You can configure the device to advertise directly-connected and static multicast routes from the
local AS to other ASs using the following methods:
•
858
[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>]
