In an embodiment, a method for automatic Open Shortest Path First (OSPF) configuration involves at a first router, receiving OSPF communications from a second router and at the first router, deriving OSPF configuration for the first router based on the received OSPF communications to match OSPF configuration of the second router. ## Claims ### Claim 1 A method for automatic Open Shortest Path First (OSPF) configuration, the method comprising: at a first router, receiving OSPF communications from a second router; and at the first router, deriving OSPF configuration for the first router based on the received OSPF communications to match OSPF configuration of the second router. ### Claim 2 (depends on 1) The method of claim 1, further comprising at the first router, transmitting OSPF communications including the derived OSPF configuration for the first router to the second router. ### Claim 3 (depends on 1) The method of claim 1, wherein the OSPF configuration for the first router comprises an OSPF area identification (ID). ### Claim 4 (depends on 1) The method of claim 1, wherein the OSPF configuration for the first router comprises an OSPF interval. ### Claim 5 (depends on 1) The method of claim 1, wherein the OSPF configuration for the first router comprises maximum transfer unit (MTU) information. ### Claim 6 (depends on 1) The method of claim 1, wherein the received OSPF communications from the second router comprise an OSPF hello packet from the second router. ### Claim 7 (depends on 6) The method of claim 6, wherein the OSPF configuration for the first router comprises an OSPF area identification (ID) that matches an OSPF ID in the OSPF hello packet from the second router. ### Claim 8 (depends on 6) The method of claim 6, wherein the OSPF configuration for the first router comprises an OSPF interval that matches an OSPF interval in the OSPF hello packet from the second router. ### Claim 9 (depends on 1) The method of claim 1, wherein the received OSPF communications from the second router comprise an OSPF database description (DD) packet from the second router. ### Claim 10 (depends on 9) The method of claim 9, wherein the OSPF configuration for the first router comprises an OSPF area identification (ID) that matches an OSPF ID in the OSPF DD packet from the second router. ### Claim 11 (depends on 9) The method of claim 9, wherein the OSPF configuration for the first router comprises maximum transfer unit (MTU) information that matches MTU information in the OSPF DD packet from the second router. ### Claim 12 (depends on 1) The method of claim 1, wherein at least one of the first and second routers comprises an Area Border Router (ABR) or an Autonomous System Border Router (ASBR). ### Claim 13 A router, the router comprising: a transceiver configured to receive OSPF communications from a second router; and a controller connected to the transceiver and configured to derive OSPF configuration for the router based on the received OSPF communications to match OSPF configuration of the second router. ### Claim 14 (depends on 13) The router of claim 13, wherein the transceiver is further configured to transmit OSPF communications including the derived OSPF configuration for the router to the second router. ### Claim 15 (depends on 13) The router of claim 13, wherein the OSPF configuration for the router comprises an OSPF area identification (ID), an OSPF interval, or maximum transfer unit (MTU) information. ### Claim 16 (depends on 13) The router of claim 13, wherein the received OSPF communications from the second router comprise an OSPF hello packet from the second router. ### Claim 17 (depends on 16) The router of claim 16, wherein the OSPF configuration for the router comprises an OSPF area identification (ID) that matches an OSPF ID in the OSPF hello packet from the second router or an OSPF interval that matches an OSPF interval in the OSPF hello packet from the second router. ### Claim 18 (depends on 13) The router of claim 13, wherein the received OSPF communications from the second router comprise an OSPF database description (DD) packet from the second router. ### Claim 19 (depends on 18) The router of claim 18, wherein the OSPF configuration for the router comprises an OSPF area identification (ID) that matches an OSPF ID in the OSPF DD packet from the second router or maximum transfer unit (MTU) information that matches MTU information in the OSPF DD packet from the second router. ### Claim 20 A method for automatic Open Shortest Path First (OSPF) configuration, the method comprising: at a first router, receiving an OSPF hello packet from a second router; and at the first router, deriving OSPF configuration for the first router from the OSPF hello packet to match OSPF configuration of the second router, wherein the OSPF configuration for the first router comprises an OSPF area identification (ID) or an OSPF interval.
