CAUTION:
On a router, all interfaces in the same VPN instance must work in the same IPv6 PIM mode.
NOTE:
For more information about the multicast ipv6 routing-enable command, see IP Multicast Command
Reference.
Enabling IPv6 BIDIR-PIM
Perform this configuration on all routers in the IPv6 BIDIR-PIM domain.
Follow these steps to enable IPv6 BIDIR-PIM:
To do... Use the command... Remarks
Enter system view system-view —
Enter IPv6 PIM view pim ipv6 —
Enable IPv6 BIDIR-PIM bidir-pim enable
Required
Disabled by default
Configuring an RP
An RP can be manually configured or dynamically elected through the BSR mechanism. For a large IPv6
PIM network, static RP configuration is a tedious job. Generally, static RP configuration is just a backup
means for the dynamic RP election mechanism to enhance the robustness and operation manageability
of a multicast network.
CAUTION:
In an IPv6 PIM network, if both IPv6 PIM-SM and IPv6 BIDIR-PIM are enabled, do not configure the same
RP to serve IPv6 PIM-SM and IPv6 BIDIR-PIM simultaneously to avoid IPv6 PIM routing table errors.
Configuring a static RP
If only one dynamic RP exists in a network, manually configuring a static RP can avoid communication
interruption due to single-point failures and avoid frequent message exchange between C-RPs and the
BSR.
Perform this configuration on all routers in the IPv6 BIDIR-PIM domain.
Follow these steps to configure a static RP:
To do… Use the command… Remarks
Enter system view system-view —
Enter IPv6 PIM view pim ipv6 —
Configure a static RP for IPv6
