Multi-Vpn Instance Ce - HP HPE FlexNetwork MSR Router Series Configuration Manual

In this scenario, PE 2 is responsible for primary link detection and traffic switchover.

VPN 1 as CE 2. When PE 2 receives an 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 2 to detect the connectivity of the public tunnel
from PE 2 to PE 3. When the tunnel 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 tunnel fails, the traffic goes through the path CE 1
—PE 1—PE 2—CE 2.
In this scenario, PE 2 is responsible for primary link detection and traffic switchover.

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.
