Detailed Descriptions of MPLS-TP

MPLS-TP LSPs

SR OS supports the configuration of MPLS-TP tunnels, which comprise a working and,
optionally, a protect LSP. In SROS, 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 (i.e. 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 given 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 via templates, in order
to simplify provisioning for large numbers of tunnels.
