5.11.5 Example for Configuring PW FRR
Networking Requirements
As shown in Figure 5-15, CE1 is single-homed to PE1. CE2 is dual-homed to PE2 and PE3.
The networking requirements are as follows:
l The CEs are connected to the PEs through Ethernet links.
l A PW is set up between PE1 and PE3. This PW is the master PW, and uses the MPLS TE
tunnel.
l A PW is set up between PE1 and PE2. This PW is the backup PW, and uses the MPLS
LSP.
l If the master link (CE2 → PE3 → P → PE1) becomes faulty, the L2VPN traffic can be
rapidly switched to the backup link (CE2 → PE2 → PE1).
l After the master link (CE2 → PE3 → P → PE1) recovers from the fault, the L2VPN traffic
is switched back.
