Abstract
A method of router interface level 2 redundancy, and router implementing the method, including one or more of the following: starting redundant ports that are members of a level 2 redundancy group (L2RG) in a DOWN state; determining that none of the redundant ports are in an ACTIVE state; switching a first one of the redundant ports to an ACTIVE state; activating an Internet protocol interface for the L2RG; inserting an Internet protocol route for an interface subnet in an FIB of a router that contains the redundant ports; binding the Internet protocol route for the interface to the first one of the redundant ports; transitioning the first one of the redundant ports to a DOWN state; transitioning the Internet protocol interface to the DOWN state from an UP state; and removing the Internet protocol route for the interface from the FIB of the router.
