Deutsche Telekom (DT) is co-authoring the draft-ietf-mpls-egress-protection-framework,  and the world-wide first ever deployment of MPLS egress protection for L3VPNs (as mentioned in NANOG71 slide deck) was implemented at DT couple of years ago. It works perfectly since then, giving ~50 ms failover during PE failures.

[JB] Thanks for all the info Krzysztof. I've read the draft and
everything is clear to me now. It turns out I already had it under the
name "draft-ietf-mpls-egress-protection-framework" in my inbox from
the IETF WG mailing list and hadn't gotten round to reading it yet. I
might have some feedback on the draft, in which case, I will post back
to the WG mailing list.

I have found PR1278535 with Juniper so I can see that bugs are being
fixed for this feature which is good to know.

I'll speak to Cisco to see if they plan on adopting the draft too.

Cheers,
James.
