Huawei quidway s7700 - Configuring Basic PIM-DM (Ipv6) Functions; Establishing the Configuration Task

l Neighbor filtering function: An interface sets up neighbor relationships with only the
addresses matching the filtering rules and deletes the neighbors unmatched with the filtering
rules
Adjusting Control Parameters for Pruning
You can adjust the following control parameters for pruning:
l The interval for keeping the Prune state of the downstream interface
l The delay from the time when the current switch receives a Prune message from a
downstream switch to the time when the current switch performs the prune action in the
LAN
l The period for overriding the prune action
Adjusting Control Parameters for State-Refresh
You can enable or disable State-Refresh, set the interval for sending PIM State-Refresh
messages, set the time for waiting to receive the next State-Refresh message, and set the TTL
values of State-Refresh messages.
Adjusting Control Parameters for Graft
You can set the interval for retransmitting Graft messages.
Adjusting Control Parameters for Assert
You can set the period for switchs to keep the Assert state. The switchs that fail in the election
forbid downstream interfaces to forward multicast data during this period. After the period
expires, the downstream interfaces continue to forward multicast data.
Configuring PIM Silent
Some hosts may send a large number of malicious PIM Hello messages, which results in the
suspension of the switch. By configuring the PIM Silent function on the interfaces of the
switch connected with the host, you can protect the switch from being attacked.
12.3 Configuring Basic PIM-DM (IPv6) Functions
Ensure that unicast routes are reachable before configuring IPv6 multicast routing and enable
IPv6 PIM-DM on each interface of the multicast device. In this manner, the IPv6 PIM-DM
network can work normally.
12.3.1 Establishing the Configuration Task
Before configuring basic IPv6 PIM-DM functions, configure a unicast IPv6 routing protocol.
Applicable Environment
PIM-DM is applicable to a small-scale network. Most of network segments have receivers.
