Increase the cryptographic key size.

Replace unicast rekey with multicast rekey.

Reduce the SAR clock interval duration

Increase the TEK and KEK lifetime.

Reduce the Dead Peer Detection periodic timer.

It provides backup convergence for all topologies by avoiding the post-convergence path

It maximizes the network utilization by load-sharing across low bandwidth and edge links while IGP convergence is in progress

No additional protocols are required in the MPLS network because it uses LDP labels to signal the backup path

Although it requires enabling segment routing, SR does not have to be activated as the preferred forwarding method

It can provide backup paths for IPv4, IPv6 and LDP traffic

MAC address learning scales better through BGP

BGP supports VPLS interworking

Pseudowire configuration overhead is reduced

There are no full-mesh pseudowire due to the route reflection feature of BGP
