[j-nsp] MPLS, RSVP and strict path

Hi Doug, 

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

We are using ISIS for the IGP and cspf statement is not configured,
afaik when you use ISIS it is not necessary to configure cspf
statement...


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

This is an example:

--> Output of show rsvp session detail on my transit router:
 
Transit RSVP: x sessions
6.0.14.5
  From: 6.0.14.7, LSPstate: Up, ActiveRoute: 1
  LSPname: MY_LSP, LSPpath: Primary
  Suggested label received: -, Suggested label sent: -
  Recovery label received: -, Recovery label sent: 0
  Resv style: 1 FF, Label in: 100016, Label out: 0
  Time left:  148, Since: Tue Apr 22 07:17:49 2008
  Tspec: rate 0bps size 0bps peak Infbps m 20 M 1500
  Port number: sender 5 receiver 34471 protocol 0
  PATH rcvfrom: 6.0.12.2 (so-6/2/0.0) 1895 pkts
  Adspec: received MTU 1500 sent MTU 1500
  PATH sentto: 6.0.12.4 (so-6/3/0.0) 1992 pkts
  RESV rcvfrom: 6.0.12.4 (so-6/3/0.0) 1954 pkts
  Explct route: 6.0.12.4 
  Record route: 6.0.12.2 <self> 6.0.12.4  

--> Configuration of the LSP on 6.0.14.7 router:
label-switched-path MY_LSP {
    to 6.0.14.5;
    primary strict-to-MY-TRANSIT-ROUTER;
}
path strict-to-MY-TRANSIT-ROUTER {
    6.0.12.1 strict;
    6.0.12.4 strict;
} 

=> 6.0.12.1 is an address of my transit router, but I don't see it in
the "show rsvp session detail" output (on transit router).


Thanks for your help,
Samuel
