[c-nsp] MPLS TE explicit-path: secondary ip as next-address

[Adam Vitkovsky]

Oh my, please why haven't you used loopback addresses in the path objects?
-do you have multiple ip mpls links between two routers and would like to
use a specific one (other than igp best path)?

Hi, List!

We need to re-number several links of our MPLS backbone network due to some
reason. And would like to minimize downtime.
We have many MPLS TE tunnesl with explicit paths configured with old ips as
next-address.

New ip addresses was configured as secondary on interfaces in question.
These new subnets (/30) appear in routing table, cef, etc. Network statement
also was added to ospf configuration.

Is it possible to somehow use these secondary ip as next-address in
explicit-paths? I'm created another one explicit path and new tunnel
interface but it's oper state is down and error is

Last Error: PCALC:: Explicit path has unknown address, x.x.x.x

This address is alive, it is in cef and mpls forwarding table.
loose mode also doesn't help.

So I think I can use only primary ip in explicit paths and can't find any
klue regarding this. IOS 12.2(33)SRD6 ADVIPSERVICES.

Googling also was helpless...

Does anybody can sheed some light on it?

Thanks in advance!
