MVPN live-live solution

We've added support to enable the MVPN live-live feature in next-generation multicast VPN (MVPN) with multicast LDP point-to-multipoint (P2MP) provider tunnel. This feature helps to keep your network live all the times.

To enable the MVPN live-live solution:

• Configure the sender-based-rpf option by running the set routing-instances routing-instance-name protocols mvpn sender-based-rpf command. This option is disabled by default.
• Configure the hot-root-standby option by running the set routing-instances routing-instance-name protocols mvpn hot-root-standby command. You can configure this option only if sender-based RPF is enabled.

When you enable this configuration, the receiving PE automatically switches over to the backup path if it encounters any failure while forwarding the traffic from the primary path to the customer network. The transition from primary path to backup path happens in less than 50 milliseconds.
