That is not the point here. What you said above is mutually exclusive.
The issue arise when you are not doing end to end encapsulation as
current UPA draft does not preclude using UPA for such networks
Hi Bruno

So the end to end encapsulation would be MPLS, SR-MPLS or SRv6 and both

Peter,
I am with you that enabling signalling UPA to the application is up to the
operator.
But going with Bruno's concern, the app (say BGP) on vendor X may use UPA
in a completely different way that on vendor Y then again on vendor Z. One
may invalidate a path with a given next hop for 5 sec

I don't see anywhere in the UPA spec even a hint that those unreachable
pulses would be installed in the IP routing table. It seems to be a local
implementation choice how ISIS or OSPF would inform other protocols about
them.

Hi Peter, hi all,
to iterate on the comment I made on the mic a few minutes ago, I
apparently have a rather different understanding of existing IS-IS
behaviour. Reading 5305/5308,

Bruno,
Actually I like your flag suggestion for an additional and different

If someone does not need to flood UPAs in any remote area it is trivial to
filter those on the ABRs connecting those areas to the core. Otherwise such
filtering could be more difficult if at all possible.
Thx,
