Enabling Mbgp; Adding Mbgp Neighbors - Dell PowerConnect B-RX Configuration Manual

Enabling MBGP

To enable MBGP4, you must enable PIM SM or DM and BGP4. Enter commands such as the
following.
BigIron RX> enable
BigIron RX# configure terminal
BigIron RX(config)# router pim
BigIron RX(config)# interface ethernet 1/1
BigIron RX(config-if-1/1)# ip address 1.1.1.1/24
BigIron RX(config-if-1/1)# ip pim
BigIron RX(config-if-1/1)# exit
BigIron RX(config)# router bgp
BGP4: Please configure 'local-as' parameter in order to enable BGP4.
BigIron RX(config-bgp)# local-as 10
The commands in this example configure PIM DM globally and on port 1/1, then enable BGP4.
Once you enable PIM DM or PIM SM both globally and on the individual RPF interfaces, and enable
BGP4, support for MBGP is automatically enabled.
Once MBGP is enabled, MBGP parameters are configured under the IPv4 multicast address family.
Enter the following command to enter the IPv4 multicast address family level.
BigIron RX(config-bgp)#address-family ipv4 multicast
BigIron RX(config-bgp-ipv4m)#
Syntax: address-family ipv4 multicast

Adding MBGP neighbors

To add an MBGP neighbor, enter a command such as the following.
BigIron RX(config-bgp-ipv4m)# neighbor 1.2.3.4 remote-as 44
This command adds a router with IP address 1.2.3.4 as an MBGP neighbor.
The remote-as 44 parameter specifies that the neighbor is in remote BGP4 AS 44. The device will
exchange only multicast routes with the neighbor.
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>
