Enabling PIM-SM
With PIM-SM enabled, a router sends hello messages periodically to discover PIM neighbors and
processes messages from the PIM neighbors. To deploy a PIM-SM domain, enable PIM-SM on all
non-border interfaces of the routers.
When the system is operating in standard mode, you must configure a reserved VLAN before you
configure PIM-SM for a VPN instance. For more information about the system operating mode, see
Fundamentals Configuration Guide. For more information about a reserved VLAN, see MPLS
Configuration Guide and MPLS Command Reference.
All the interfaces of a switch that are in the same VPN instance must share the same PIM mode.
