R2511-HP MSR Router Series MPLS Configuration Guide(V5)

# Create a Martini VC on the interface connected to CE 2. The interface requires no IP address.

5. On CE 2, configure the link protocol type as PPP on interface Serial 2/0 (the interface connected

to the PE 1), and configure an IP address for the interface.

Configuring Martini VC redundancy

Network requirements

The CEs are connected to the PEs through serial interfaces and PPP encapsulation is used at the link layer.

Create two Martini VCs between CE 1 and CE 2, one is CE 1 – PE 1 – PE 2 – CE 2 (the primary VC) and

the other is CE 1 – PE 1 – PE 3 – CE 2 (the backup VC).
