A method, system and device of Transparent Interconnection of Lots of Links (TRILL) network communications across an Internet Protocol (IP) network are provided. The method includes: DC1 and DC2 which are respectively a local and remote Data Center (DC) networks connected with each other via the IP network; DC1 and DC2 are respectively deployed with a TRILL network; a first DCI device (S1, S2) is an RBridge located in core layer of TRILL network in DC1; a first access layer device (S10, S11, S20) is any RBridge located in access layer of TRILL network in DC1; a second DCI device (S1, S2) is an RBridge located in core layer of TRILL network of DC2; a second access layer device (S30, S31, S40) is an RBridge located in access layer of TRILL network in DC2; generating, by the first DCI device (S1, S2), a nickname forwarding table by learning routes to RBridges in local and remote TRILL networks, after receiving a packet destined for DC2 or sent by DC2, forwarding, by the first DCI device (S1, S2), the packet according to the nickname forwarding table. |
