BGP Fast Reroute is triggered by IGP events.

The backup path is pre-computed and installed in the FIB.

BGP Fast Reroute is independent of number of affected prefixes.

BGP Fast Reroute uses the optimal path to the destination.

VPLS 100 was not actually configured as a management VPLS.

VPLS 10 and VPLS 20 are not actually configured as a user VPLS.

VPLS 10 and VPLS 20 are not using the same spoke-sdps that the management VPLS is using.

Based on the output there is now way of telling if there is a problem with the configuration.

The receiving PE checks the l-TAG in the l-SID to determine if there is a local l-VPLS on the node.

The receiving PE checks the l-SID in the l-TAG to determine if there is a local l-VPLS on the node.

The receiving PE checks the service label in the mpls header to determine if there is a local l-VPLS on the node.

The receiving PE checks the multicast B-DA to see if an l-SID has been mapped to the B-DA that matches a local l-VPLS on the node.

It flushes the local FDB speeding recovery

It discards all packets in the queue and sends icmp-discad messages to the sender. The packets are re-transmitted resulting in no loss of data.

On failure, the PE sends an LDP flush-all-from-me message to all PE devices in the VPLS. This speeds convergence to the new topology.

It is not important to use send-flush-on-failure as Active/Standby signalling automatically converges the FDB in all VPLS instances
