Hello !

You are looking for the problem on the wrong node the other node seems to be
missing soemthing

Unfortunately the error messages in the IOS are not reflecting what really
is the problem.
but it is not the address , it is the missing TE config parts on the other
node
so have look there ( missing TE area, missing TE router id missing mpls tra
tu on interface,...)

PCALC means that the programm calculating a path has detected the problem
even before traying to setup a tunnel via RSVP.

so you can also look into "sho mpls tra topology"

the main differnece to the working tunnels is, that the dynamic one needs to
get TE-info via OSPF extensions (LSPs with also BW and reservation
information) and then calculates a possible path to that destination.

with best regards

Alexander

Subject: (Resend) Cisco MPLS configuration - PCALC:: Destination IP
address not found


Question to those familiar with Cisco's MPLS implementation and how it's
configured. I'm trying to establish an LSP *from* Cisco *to* another box
directly connectioned on the FA 0/1. See my comments prefixed with "***"

*** Running IOS (tm) 7200 Software (C7200-P-M), Version 12.1(5)T4,
RELEASE SOFTWARE (fc1) on a Cisco 7306, I cannot seem to get an outgoing
tunnel to come up.

*** Anyone understand the "PCALC" error? I believe this is an OSPF path
calculation which is failing. Here is the OSPF database.

*** I am trying to get the Cisco to send the RSVP PATH request but this
error seems to prevent it. Anyone see what I'm doing wrong? Any
suggestions as to how to further isolate the issue? Thanks.
