Field

Default

Control command

VLAN

N/A

vlan vid ip pim-dense

IP

N/A

vlan vid ip pim-dense any | ip-addr

Mode

dense

PIM-dense or PIM-sparse

Hello interval (sec)

30

ip pim-dense hello interval 5 - 30

Hello hold time

105

The routing switch computes this value from the current hello interval and includes it in the hello packets the routing switch sends to neighbor routers. Neighbor routers use this value to determine how long to wait for another hello packet from the routing switch. See the description of the hello interval on PIM VLAN (interface) configuration context.

Hello delay

5

vlan vid ip pim-dense hello delay 0 - 5

Graft retry interval (sec)

3

vlan vid ip pim-dense graft-retry-interval 1 - 10

Max graft retries

2

vlan vid ip pim-dense graft-retries 1 - 10

Override interval (msec)

2500

vlan vid ip pim-dense override-interval 500 - 6000

Propagation delay (msec)

500

vlan vid ip pim-dense propagation-delay 250-2000

SR TTL threshold (router hops)

0

vlan vid ip pim-dense ttl-threshold 0 - 255

LAN prune delay

Yes

vlan vid ip pim-dense lan-prune-delay

LAN delay enabled

No

Shows

[Yes]
if all multicast routers on the current VLAN interface enabled LAN-prune-delay. Otherwise, shows

No

State-refresh capable

N/A

Indicates whether the VLAN responds to state-refresh packets. The VLAN connected to the multicast source does not receive state-refresh packets and thus is not state-refresh capable. Downstream VLANs in the switches are state-refresh capable.
