本发明公开了一种MPLS TE隧道故障检测方法及其设备,包括:入节点向出节点发送第一RSVP报文,以使出节点获取第一RSVP报文中携带的前向隧道的lsr-id,前向隧道的隧道标识以及检测报文的类型信息,并根据第一RSVP报文中携带的信息确定前向隧道对应的反向隧道;入节点接收出节点响应的第二RSVP报文,并获取第二RSVP报文中携带...
The embodiment of the invention provides a multiprotocol label switching traffic engineering tunnel building method and device. The tunnel building method comprises the following steps: a first router device receives identifiers of an MPLS (multi-protocol label switching) TE (traffic engineering) tunnel ...
and role information thereof, then determining whether they belong to the same Mesh Group according to the information about the Mesh Groups to which they belong; and after determining that they belong to the same Mesh Group, determining whether to establish an MPLS TE tunnel to the second PE....
After determining that the two belong to the same Mesh Group, the first PE determines, according to role information of the two, whether to establish the MPLS TE tunnel to the second PE.doi:US20150085638Zhenbin Li
In the technical solutions of the present invention, the MpLS TE tunnel is established according to both information of a Mesh Group to which a PE belongs and role information of the PE, which avoids establishing an unnecessary MPLS TE tunnel, and overcomes a limitation in establishing the MPLS...
HIERARCHICAL MPLS (MULTI PROTOCOL LABEL SWITCHING) NETWORK TUNNEL COMMUNICATION METHODPROBLEM TO BE SOLVED: To attain tunnel setting of an LSP of the P2P and the P2MP to a TE-LSP group for building up a hierarchical logical service network.YASUKAWA MASANAGA...
After determining that the two belong to the same Mesh Group, the first PE determines, according to role information of the two, whether to establish the MPLS TE tunnel to the second PE.LI, Zhenbin
A tunnel establishing method includes: receiving, by a second routing device, an identifier, which is sent by a first routing device, of an MPLS TE tunnel from a first VPN instance to a second VPN instance; acquiring, by the second routing device according to the identifier, path information...
