Abstract
In one aspect, a method includes determining, at a first node in an active state, a local wide area network (WAN) tunnel state of a WAN tunnel of the first node based on a forwarding table of the first node; determining, at the first node, a local direct internet access (DIA) path state of a DIA path of the first node based on a DIA tracker; receiving, at the first node, state information associated with a second node, wherein the state information includes a far-end WAN tunnel state and a far-end DIA path state associated with the second node; comparing, at the first node, the local WAN tunnel state and the local DIA path state with the far-end WAN tunnel state and the far-end DIA path state of the second node, respectively to yield a comparison; and based on the comparison, switching, by the first node, to a standby state.
