through the path CE 1—PE 1—PE 2—PE 3—CE 2. This avoids traffic interruption before route
convergence completes (switching back to the link CE 1—PE 1—PE 3—CE 2).
In this scenario, PE 2 is responsible for primary link detection and traffic switchover.

As shown in
IPv4 route from CE 2 and a VPNv4 route from PE 3 (both routes are destined for VPN 1 connected to CE
2), PE 2 uses the VPNv4 route as the primary link, and the IPv4 route as the backup link.
Configure BFD for LSPs or MPLS TE tunnels on PE to detect the connectivity of the LSP tunnel between PE
2 and PE 3. When the link operates correctly, traffic from CE 1 to CE 2 goes through the path CE 1—
PE 1—PE 2—PE 3—CE 2. When the link fails, the traffic goes through the path CE 1—PE 1—PE 2—
CE 2.

Multi-VPN instance CE

The Multi-VPN Instance CE (MCE) feature allows you to create multiple VPN instances on a CE. The VPN
instances each have an independent routing table and an address space to achieve service isolation.
