Configuring a static multicast route
19
NOTE
The ethernet <portnum> parameter does not apply to PIM SM.
The distance <num> parameter sets the administrative distance for the route. When comparing
multiple paths for a route, the Layer 3 Switch prefers the path with the lower administrative
distance.
NOTE
Regardless of the administrative distances, the Layer 3 Switch always prefers directly connected
routes over other routes.
The rpf_address <rpf-num> parameter specifies an RPF number.
The example above configures two static multicast routes. The first route is for a specific source
network, 207.95.10.0/24. If the Layer 3 Switch receives multicast traffic for network
207.95.10.0/24, the traffic must arrive on port 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 3.
Figure 91 shows an example of an IP Multicast network. The two static routes configured in the
example above apply to this network. The commands in the example above configure PIM router A
to accept PIM packets from 207.95.10.0/24 when they use the path that arrives at port 2, and
accept all other PIM packets only when they use the path that arrives at port 3.
The distance parameter sets the administrative distance. This parameter is used by the software to
determine the best path for the route. Thus, to ensure that the Layer 3 Switch uses the default
static route, assign a low administrative distance value. When comparing multiple paths for a route,
the Layer 3 Switch prefers the path with the lower administrative distance.
FIGURE 91 Example of multicast static routes
To add a static route to a virtual interface, enter commands such as the following.
