(Optional) Configuring Ethernet over GRE Reliability

Context

A VE interface will become invalid if the card where the interface resides is faulty or absent. In this case, services will be interrupted. To solve this problem, a tunnel interface on a switch can be bound to two VE interfaces. Only one VE interface takes effect at a time. If a VE interface fails, traffic is switched to the other VE interface.

Procedure

  • Perform operations in Configuring Basic Ethernet over GRE Functions repeatedly to configure two VE interfaces and bind them to the same tunnel interface.

    NOTE:

    Ensure that the two VE interfaces have the same configuration.

    If the faulty VE interface becomes valid again, service traffic will not be switched back to it.
