The 7705 SAR supports static and dynamic LSPs.
To configure MPLS-signaled (dynamic) LSPs, the LSP must run from an ingress LER to an egress LER. Configure the dynamic LSP only at the ingress router, and either configure the LSP to allow the router software to make the forwarding decisions or configure some or all routers in the LSP path statically. The LSP is set up by RSVP-TE signaling messages. The 7705 SAR automatically manages label values. Labels that are automatically assigned have values ranging from 1024 through 1 048 575 (see Label Values).
A static LSP is a manually configured LSP where the next hop IP address and the outgoing label are explicitly specified.
To establish a static LSP, an LSP must be configured from an ingress LER to an egress LER. Labels must be manually assigned and the label values must be within the range of 32 to 1023 (see Label Values).
