Abstract
In an example embodiment disclosed herein, Wide Area Network optimization modules coupled to peers are configured to maintain peer routing tables. The peer routing table (PRT) is used by the Wide Area Network optimization module to determine the peer for a given destination, such as an Internet Protocol 'IP' destination. Each peer is responsible for advertising to other peers which networks the peer is able to reach. This information is advertised when a tunnel is first created and subsequently whenever necessary. Initially, a peer sends out a list of entries corresponding to its directly connected networks, with the exception of the network connected to the interface on which the peer is advertising (e.g. the network used for the tunnel). This enables other peers on the network to populate their PRT entries.
