Abstract:
A method for recovering service forward routing includes the steps of: suppressing the service forward routing on a standby link from changing during a routing learning process when a primary link recovers from a fault state to a normal state, establishing a label distribution protocol (LDP) session on the primary link, and redirecting the service forward routing on the standby link to the primary link after the LDP session on the primary link is established.
