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.
Claims16
A method for recovering service forward routing, comprising the steps of:
- suppressing 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.
1 more element
A system for recovering service forward routing, comprising:
- a routing change suppressing unit, configured to suppress the service forward routing on a standby link from changing during a routing learning process when a primary link recovers from fault state to normal state;
- an LDP session establishing unit, configured to establish an LDP session on the primary link during the process in which the routing change suppressing unit suppresses the service forward routing on a standby link from changing;
- and
- a routing redirecting unit, configured to redirect the service forward routing on the standby link to the primary link after the LDP session establishing unit has established an LDP session on the primary link.
