forwarding any PIM-IPv6 packet. All PIM-IPv6 neighbors and PIM-IPv6 state machines on the
interface are deleted. The interface acts as the static DR and immediately takes effect. At the
same time, MLD on the interface is not affected.
To enable PIM-IPv6 silent, the network environment must meet the following conditions:
l The network supports IPv4 and IPv6.
l The PIM-IPv6 silent is applicable only to the switch interface directly connected to the host
network segment that is connected only to this switch.
CAUTION
If PIM-IPv6 silent is enabled on the interface connected to a switch, the PIM-IPv6 neighbor
cannot be established and a multicast fault may occur.
If the host network segment is connected to multiple switchs and PIM-IPv6 silent is enabled on
multiple switch interfaces, the interface become static DRs. Therefore, multiple DRs exist in
this network segment, and a multicast fault occurs.
Pre-configuration Tasks
Before configuring PIM-IPv6 silent, complete the following tasks:
l Configuring a unicast routing protocol to make the network layer reachable
l Configuring PIM-SM
l Configuring MLD
Data Preparation
To configure PIM-IPv6 silent, you need the following data.
No.
Data
1 The number of the switch interface connected to hosts
13.12.2 Configuring PIM-IPv6 Silent
After the interface is configured with PIM silent, it is forbidden to receive or forward any PIM
protocol packet. All PIM neighbors and PIM state machines on this interface are deleted. Then,
this interface automatically becomes the DR. MLD on the interface is not affected.
Context
CAUTION
PIM-IPv6 silent is applicable only to the switch interface connected to the host network segment
that can be connected to only one PIM-IPv6 switch.
