Upstream LSPs

[MATSUURA Nobuaki <matsuura.nobuaki@lab.ntt.co.jp>]

Hi,

According to the gmpls-rsvp standard documents, an upstream LSP is established
before RSBs are built on nodes along the path. In other words, upstream LSPs are
based on only PSBs and maintained by refresh Path massages. 
So in a case of failed RSBs, upstream LSPs that are implemented by the protocol
(not an operational policy) would remain. Is it a problem should be fixed?

I think it is rather meaningful to use this for unidirectional LSPs as a normal status.
Please take a look at

Thanks,
