The 7210 SAS supports the configuration of MPLS-TP tunnels, which comprise a working and, optionally, a protect LSP. In 7210 SAS, a tunnel is referred to as an LSP, while an MPLS-TP LSP is referred to as a path. It is then possible to bind an MPLS-TP tunnel to an SDP.
MPLS-TP LSPs (that is, paths) with static labels are supported. MPLS-TP is not supported for signaled LSPs.
Both bidirectional associated (where the forward and reverse directions of a bidirectional LSP are associated at a specific LER, but may take different routes through the intervening network) and bidirectional co-routed (where the forward and reverse directions of the LSP are associated at each LSR, and take the same route through the network) are possible in MPLS-TP. However, only bidirectional co-routed LSPs are supported.
It is possible to configure MPLS-TP identifiers associated with the LSP, and MPLS-TP OAM parameters on each LSP of a tunnel. MPLS-TP protection is configured for a tunnel at the level of the protect path level. Both protection and OAM configuration is managed through templates to simplify provisioning for a large numbers of tunnels.
The 7210 SAS plays the role of either an LER or an LSR.
