ipv6 pim state-refresh
origination-interval
This command sets the interval between sending PIM-DM state refresh control
messages. Use the no form to restore the default value.
Syntax
ipv6 pim state-refresh origination-interval seconds
no ipv6 pim max-graft-retries
seconds - The interval between sending PIM-DM state refresh control
messages. (Range: 1-100 seconds)
Default Setting
60 seconds
Command Mode
Interface Configuration (VLAN)
Command Usage
â—† The pruned state times out approximately every three minutes and the entire
PIM-DM network is reflooded with multicast packets and prune messages. The
state refresh feature keeps the pruned state from timing out by periodically
forwarding a control message down the distribution tree, refreshing the prune
state on the outgoing interfaces of each router in the tree. This also enables PIM
routers to recognize topology changes (sources joining or leaving a multicast
group) before the default three-minute state timeout expires.
â—† This command is only effectively for interfaces of first hop, PIM-DM routers that
are directly connected to sources of multicast groups.
Example
Console(config-if)#ipv6 pim state-refresh origination-interval 30
Console(config-if)#
PIM6-SM Commands
ipv6 pim
bsr-candidate
This command configures the switch as a Bootstrap Router (BSR) candidate. Use the
no form to restore the default value.
Syntax
ipv6 pim bsr-candidate interface vlan vlan-id [hash hash-mask-length]
[priority priority]
no ipv6 pim bsr-candidate
vlan-id - VLAN ID (Range: 1-4094)
hash-mask-length - Hash mask length (in bits) used for RP selection (see
ipv6 pim rp-candidate and ipv6 pim rp-address). The portion of the hash
specified by the mask length is ANDed with the group address. Therefore,
