Configuring MBGP
NOTE
The route map you specify must already be configured.
Configuring static IP multicast routes
To configure static IP multicast routes, enter commands such as the following.
BigIron RX(config)# ip mroute 207.95.10.0 255.255.255.0 interface ethernet 1/2
BigIron RX(config)# ip mroute 0.0.0.0 0.0.0.0 interface ethernet 2/3
The commands in this example configure two static multicast routes. The first route is for a specific
source network, 207.95.10.0/24. If the device receives multicast traffic for network
207.95.10.0/24, the traffic must arrive on port 1/2. The second route is for all other multicast
traffic. Traffic from multicast sources other than 207.95.10.0/24 must arrive on port 2/3.
If you configure more than one static multicast route, the device always uses the most specific
route that matches a multicast source address. Thus, if you want to configure a multicast static
route for a specific multicast source and also configure another multicast static route for all other
sources, you can configure two static routes as shown in this example.
Syntax: [no] ip mroute <ip-addr> <ip-mask> [<next-hop-ip-addr> | ethernet <slot/port> | ve
The ip-addr and ip-mask parameters specifies the PIM source for the route.
The ethernet <slot/port> parameter specifies a physical port.
The ve <num> parameter specifies a virtual interface.
The null0 parameter is the same as dropping the traffic.
The distance <num> parameter sets the administrative distance for the route.
The <cost> parameter specifies the cost metric of the route.
Possible values are: 1 - 6
Default value: 1
NOTE
Regardless of the administrative distances, the device always prefers directly connected routes over
other routes.
Aggregating routes advertised to BGP4 neighbors
By default, the BigIron RX advertises individual MBGP routes for all the multicast networks. The
aggregation feature allows you to configure the device to aggregate routes in a range of networks
into a single CIDR number. For example, without aggregation, the device will individually advertise
routes for networks 207.95.10.0/24, 207.95.20.0/24, and 207.95.30.0/24. You can configure the
device to instead send a single, aggregate route for the networks. The aggregate route would be
advertised as 207.95.0.0/16.
To aggregate MBGP routes for 207.95.10.0/24, 207.95.20.0/24, and 207.95.30.0/24, enter the
following command.
BigIron RX(config-bgp-router)# aggregate-address 207.95.0.0 255.255.0.0
Syntax: aggregate-address <ip-addr> <ip-mask> [as-set] [summary-only] [suppress-map
