[j-nsp] MPLS, RSVP and strict path

[Doug Marschke]

Are you using cspf or non-cspf? If you are using cspf the router will always spit out strict nodes.

Only way I know is show rsvp session detail and match on a series of ip addresses.

Unfortunetely I can't change the configuration for it.
About the command "show rsvp session" I don't see ERO information.

This is my "problem" in detail.
In fact I am doing some migrations to install a new Juniper router. During a short period the routers (old and new one) are beside and when the migration is finished I power off the old one. 
To put this new router in the network I use a new loopback address. I need to know the stricts LSPs going through the old router, to configure the new loopback on the ingress routers (if loopback is used in the path).
Currently I use the command "show mpls lsp transit" to know which LSPs are in transit and after I go on each router where come from the LSPs to know if a strict path with the old loopback is configured. I would like to find a way to simplify this.

Thanks,
Samuel

Look at the ERO using trace-options or show rsvp session.

Hi Group,
 
Do you know a easy way to see if a LSP going through a transit router is configured with a strict path ?
 
Thanks for your help,
Samuel
