Abstract

A network device, is to be deployed in a network between a first network domain and a second network domain, and is to be configured for fast reroute. The network device includes a first traffic forwarder control module, corresponding to the first network domain, which is to determine a primary next hop in the first network domain. The control plane includes a second traffic forwarder control module, corresponding to the second network domain, which is to determine a backup next hop in the second network domain. The backup next hop is to be used as a fast reroute for the primary next hop in response to a failure associated with the primary next hop. The control plane includes a controller module, in communication with the first and second traffic forwarder control modules, which is to configure a forwarding structure of the forwarding plane with the primary and backup next hops.
