Abstract
A method for implementing operation, administration and maintenance (OAM), a routing bridge (RB) and a Transparent Interconnection of Lots of Links (TRILL) network are described. A designated virtual local area network identifier (DVLAN ID) of a TRILL network is designated to be used for TRILL OAM, so that an inner virtual local area network identifier (VLAN ID) and an outer VLAN ID of a TRILL OAM packet are both a DVLAN ID, thereby ensuring availability of a TRILL OAM function.

A method for implementing operation, administration and maintenance (OAM) on a Transparent Interconnection of Lots of Links (TRILL) network by an ingress routing bridge (RB), comprising:
- generating a first TRILL OAM packet through encapsulation, wherein an inner virtual local area network identifier (VLAN ID) and an outer VLAN ID of the first TRILL OAM packet are a designated virtual local area network identifier (DVLAN ID) of the TRILL network, wherein the ingress RB resides on the TRILL network, wherein an inner destination media access control (MAC) address of the first TRILL OAM packet is a MAC address of an egress RB, wherein an ingress RB nickname in a TRILL header of the first TRILL OAM packet is a nickname of the ingress RB, and wherein an egress RB nickname in the TRILL header of the first TRILL OAM packet is a nickname of the egress RB;
- and
- sending the first TRILL OAM packet to the egress RB so that the egress RB processes the first TRILL OAM packet.
A routing bridge (RB) in a Transparent Interconnection of Lots of Links (TRILL) network, comprising:
- an encapsulating module configured to generate a first TRILL operation, administration and maintenance (OAM) packet through encapsulation, wherein an inner local area network identifier (VLAN ID) and an outer VLAN ID of the first TRILL OAM packet are a designated virtual local area network identifier (DVLAN ID) of the TRILL network, wherein the RB resides on the TRILL network, wherein an inner destination media access control (MAC) address of the first TRILL OAM packet is a MAC address of an egress RB, and wherein an egress RB nickname in a TRILL header of the first TRILL OAM packet is a nickname of the egress RB;
- and
- a sending module configured to send the first TRILL OAM packet to the egress RB, so that the egress RB processes the first TRILL OAM packet.
A Transparent Interconnection of Lots of Links (TRILL) network, comprising:
- an ingress routing bridge (RB), wherein the ingress RB is configured to:
- generate a first TRILL operation, administration and maintenance (OAM) packet through encapsulation;
- and
- send the first TRILL OAM packet to an egress RB, wherein an inner virtual local area network identifier (VLAN ID) and an outer VLAN ID of the first TRILL OAM packet are a designated virtual local area network identifier (DVLAN ID) of the TRILL network, wherein an inner destination media access control (MAC) address of the first TRILL OAM packet is a MAC address of the egress RB, wherein an ingress RB nickname in a TRILL header of the first TRILL OAM packet is a nickname of the ingress RB, and wherein an egress RB nickname in the TRILL header of the first TRILL OAM packet is a nickname of the egress RB;
- and
- an egress RB, wherein the egress RB is configured to:
- receive the first TRILL OAM packet;
- perform TRILL decapsulation on the TRILL OAM packet to obtain a first OAM packet;
- and
- process the first OAM packet.
