Configuring PIM-SM support in a VLAN context
PIM-SM support must be configured in each VLAN
where you want PIM-SM forwarding of multicast traffic. This illustrates
the following per-VLAN configuration steps:
Enabling PIM-SM on VLAN 120 and allowing the default
any
option to select a source IP address for PIM-SM packets forwarded from this VLAN. (Because the VLAN in this example is configured with only one IP address—120-10.10.2—it is this address that will be used for the source.)Increasing the DR priority on this VLAN from the default 1 to 100.
Leaving the other per-VLAN PIM-SM fields in their default settings.
