Configuring MBGP
Adding MBGP neighbors
To add an MBGP neighbor, enter a command such as the following.
Brocade(config-bgp-ipv4m)#neighbor 10.2.3.4 remote-as 44
This command adds a router with IP address 10.2.3.4 as an MBGP neighbor.
The remote-as 44 parameter specifies that the neighbor is in remote BGP4 AS 44. The Brocade
device will exchange only multicast routes with the neighbor.
NOTE
If the Brocade device 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
[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 [generate-rib-out]]
[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. Make sure you enter
the IP address in the correct address family format.
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 Brocade device 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 Brocade device establishes a session with the neighbor, you can
administratively shut down the neighbor.
