Huawei Quidway S9300

l A PW is set up between PE1 and PE2. This PW is the backup PW, and uses the MPLS LSP
tunnel.
l If the master link (CE2 → PE3 → PE1) becomes faulty, the L2VPN traffic can be rapidly
switched to the backup link (CE2 → PE2 → PE1).
l After the master link (CE2 → PE3 → PE1) recovers from the fault, the L2VPN traffic is
switched back.
