With the tests and applications of IP Radio Access Networks（IPRAN）

there emerge many complex application scenes

e.g.full layer2PWE3for inter-ring protection of double node cross-ring service and using MS-PW and DNI protection or L2VPN transferred to L3VPN service.For these scenes

the conventional configurations are very complicated in modes and process.This paper introduces the complicated configuration steps of IPRAN in the above-mentioned scenes and presents the mapping substitution of the key nodes with a service scene template

incorporating all the tunnel

PW

PW redundancy and DNI that are required by the services rapidly once for all and thus improving the efficiency of E2E static service assignment in such scenes.
