This feature is only supported on the 7210 SAS-Mxp. Only P2P LSPs are supported; P2MP LSPs are not supported.
The inter-area contiguous LSP functionality provides an end-to-end TE path. Each transit node in an area can set up a TE path LSP that is based on TE information available within its local area.
A PE node that initiates an inter-area contiguous TE LSP does a partial CSPF calculation to include its local area border router (ABR) as a loose node.
An ABR that receives a Path message with loose hop ERO does a partial CSPF calculation to the next domain border router as a loose hop or CSPF to reach the final destination.
