Configuring MBGP
28
To increase the maximum number of multicast routes supported on the device, enter commands
such as the following.
BigIron RX(config)# system-max multicast-route 12000
BigIron RX(config)# write memory
BigIron RX(config)# end
BigIron RX# reload
These commands increase the maximum number of multicast routes supported, save the
configuration change to the startup-config file, and reload the software to place the change into
effect.
Syntax: [no] system-max multicast-route <num>
The <num> parameter specifies the number of multicast routes and can be from 1024 – 153,600.
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 default-network 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.
