Question

You are deploying an EoMPLS point-to-point pseudowire (VPWS) between two IOS XR PE routers across a core that performs equal-cost load balancing based on a deep packet hash. Customers report intermittent packet reordering and dropped frames on the emulated Ethernet circuit, though the pseudowire is up on both ends. What should you configure on the pseudowire to resolve this issue?

Accepted Answer

Enable the control word on the pseudowire at both PEs

Answer

Change the pseudowire encapsulation type from Ethernet to VLAN mode

Answer

Increase the MTU on the attachment circuits to accommodate the label stack

Answer

Configure a static pseudowire label instead of using LDP signaling
