Configuration considerations

•
You can configure an aggregate address to aggregate network prefixes into a single, more general
prefix for advertisement.
MBGP is described in detail in RFC 2858.

Configuring MBGP

1. Optional – Set the maximum number of multicast routes supported by the device.
2. Enable MBGP by doing the following:
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.
8. Save the configuration changes to the startup-config file.
Setting the maximum number of multicast routes supported
The device supports up 1024 – 153,600 multicast routes.
NOTE
This procedure requires a software reload to place the change into effect.
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
856
Directly-connected multicast routes redistributed into MBGP.
MBGP does not redistribute DVMRP routes. It redistributes static routes only.
You cannot redistribute MBGP routes into BGP4.
The device supports 8192 multicast routes by default. You may need to increase the
maximum number of multicast routes for MBGP. You can configure the device to support up to
153,600 multicast routes.
•
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 device
in order for the device to send multicast prefixes to other multicast routers.
•
Enable BGP4. If this is the first time you have configured BGP4 on this device, you also
need to specify the local AS number.
Optional – Configure a route map to apply routing policy to multicast routes.
