Abstract
In an embodiment, a method exchanges routing data within a network including control and forwarding on separate devices. In the method, a first reachability information session is established between a forwarding device and a first control device and a second reachability information session is established between the forwarding device and a second control device. Also, a third reachability information session is established between the forwarding device and an external routing device. Finally, advertisements are exchanged between the first and second reachability information sessions and the third reachability information session such that the first and second control device appear to the external routing device to be a single device. System and computer program product embodiments are also disclosed.
