Configuring Ipv6 Pim-Dm Graft Retry Period; Configuring Ipv6 Pim-Sm; Prerequisites - HP A6600 Configuration Manual

state-refresh message might cycle in the network. To control the propagation scope of state-refresh
messages, you must configure an appropriate hop limit value based on the network size.
Perform the following configurations on all routers in the IPv6 PIM domain.
To do...
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure the interval
between state-refresh
messages.
4. Configure the time to wait
before receiving a new
state-refresh message.
5. Configure the hop limit value
of state-refresh messages.

Configuring IPv6 PIM-DM graft retry period

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—namely, graft retry period—until it receives a graft-ack message from the upstream
router.
To do...
1. Enter system view.
2. Enter interface view.
3. Configure graft retry period.
For more information about the configuration of other timers in IPv6 PIM-DM, see
common timers."

Configuring IPv6 PIM-SM

Prerequisites

Before configuring IPv6 PIM-SM, complete the following tasks:
Enable IPv6 forwarding and configure an IPv6 unicast routing protocol so that all devices in the
•
domain are interoperable at the network layer
• Determine the IP address of a static RP and the ACL rule defining the range of IPv6 multicast groups
to be served by the static RP
Determine the C-RP priority and the ACL rule defining the range of IPv6 multicast groups to be
•
served by each C-RP
Use the command...
system-view
pim ipv6

state-refresh-rate-limit interval
