Configuration considerations
Configuration considerations
The configuration considerations are as follows:
• MBGP does not redistribute DVMRP routes. It redistributes static routes only.
• You cannot redistribute MBGP routes into BGP4.
• By default, the Brocade device does not place a limit any limit on the number of multicast
routes. You can configure the device to place a limit on the number of multicast routes by using
the ip max-mroute command.
• IPv4 multicast RPF on Brocade NetIron CER and Brocade NetIron CES devices is based on
VLAN.
• IPv4 and IPv6 multicast RPF on Brocade MLX series and Brocade NetIron XMR devices is
based on VLAN and port.
Configuring MBGP
1. Optional – Set the maximum number of multicast routes supported by the Brocade device.
2. Enable MBGP by doing the following:
• Enable PIM Sparse Mode (PIM SM) or PIM Dense Mode (PIM DM) globally and on the
individual Reverse Path Forwarding (RPF) interfaces. PIM must be running on the Brocade
device in order for the device to send multicast prefixes to other multicast devices.
• Enable BGP4. If this is the first time you have configured BGP4 on this device, you also
need to specify the local AS number.
3. Identify the neighboring MBGP routers.
4. Optional – Configure an MBGP default route.
5. Optional – Configure an IP multicast static route.
6. Optional – Configure an MBGP aggregate address.
7. Optional – Configure a route map to apply routing policy to multicast routes.
8. Save the configuration changes to the startup-config file.
Setting the maximum number of multicast
routes supported
NOTE
This procedure requires a software reload to place the change into effect.
You can use the following runtime command to define the maximum number of multicast routes
supported. This parameter can be defined for the default VRF using the following command.
Brocade(config)# ip max-mroute
Brocade(config)# write memory
Brocade(config)# end
Brocade# reload
