1410 Managing IPv4 and IPv6 Multicast
Configuring and Viewing PIM-SM for IPv4 Multicast Routing
Beginning in Privileged EXEC mode, use the following commands to
configure PIM-SM for IPv4 multicast routing on the switch and on VLAN
routing interfaces and to view PIM-SM information.
Command Purpose
configure Enter global configuration mode.
ip routing Enable ip routing. Routing is required for PIM
operation.
ip pim sparse Enable PIM-SM as the multicast routing protocol on
the switch.
ip igmp Enable IGMP.
ip multicast Enable IPv4/IPv6 multicast routing.

Configure the switch to announce its candidacy as a
bootstrap router (BSR).
•
vlan-id
— A valid VLAN ID.
•
hash-mask-length
— The length of a mask that is to
be ANDed with the group address before the hash
function is called. All groups with the same seed
hash correspond to the same RP. For example, if this
value is 24, only the first 24 bits of the group
addresses matter. This allows you to get one RP for
multiple groups. (Range 0–32 bits).
•
priority
— The priority of the candidate BSR. The
BSR with the higher priority is preferred. If the
priority values are the same, the router with the
higher IP address is the BSR. (Range 0–255).
•
interval —
(Optional) Indicates the BSR candidate
advertisement interval. The range is from 1 to 16383
seconds. The default value is 60 seconds.
