5. Configure the hop limit value
of state refresh messages.

By default, the hop limit value of
state refresh messages is 255.
Configuring IPv6 PIM-DM graft retry timer
In IPv6 PIM-DM, graft is the only type of message that uses the acknowledgment mechanism. In an IPv6
PIM-DM domain, if a router does not receive a graft-ack message from the upstream router within the
specified time after it sends a graft message, the router keeps sending new graft messages at a
configurable interval (graft retry timer) until it receives a graft-ack message from the upstream router. For
more information about the configuration of other timers in IPv6 PIM-DM, see "Configuring common IPv6
PI
M timers."
To configure the IPv6 PIM-DM graft retry timer:

Configuring IPv6 PIM-SM
IPv6 PIM-SM configuration task list
Task at a
g
lance
(Required.) Enabling IPv6 PIM-SM
(Required.) Configuring an RP:
• Configuring a static RP
• Configuring a C-RP
NOTE:
Perform at least one of the tasks.
In a network with a static RP, skip the task of configuring a BSR.
Configure a BSR:
• (Required.) Configuring a C-BSR
• (Optional.) Configuring an IPv6 PIM domain border
• (Optional.) Disabling the BSM semantic fragmentation function
(Optional.) Configuring IPv6 multicast source registration
(Optional.) Configuring switchover to SPT
(Optional.) Configuring common IPv6 PIM features
