Assumption for the simplicity Switching capability (SC) must be consistent from an ingress node to an egress node [smaller switching granularity at ingress/egress nodes]. Switching capability of transit nodes must be consistent with switching capability of a LSP to be created (not multi-layer). Encoding-type must be consistent along a route to be established. |
