I've seen numerous topics about this, but I wanted to touch base to see if the view has changed or what the latest is on this? I have a customer that's wanting to do the following:
CE --- PE --- PE --- CE
Standard MPLS configuration, nothing fancy here. After the VPNv4 peering between the PE's, they want to run IS-IS as their IGP to redistribute into BGP. Everything that I've read says that IS-IS as an IGP for PE-CE route exchange is not supported.
Here is a thread talking about this, but it's somewhat old:

Any feedback is appreciated!

Hi
IS-IS isn't supported on a PE-CE design. As far as I know it's always in a draft Internet publication.
You can use all others protocols.
I used to implement 80% of the time BGP, but I've also used OSPF and EIGRP.
1 time in the last 10 years I've been asked to build it in RIPv2.
Thanks

I think VRF aware IS-IS is supported on IOS devices but not on XR. So you can possibly used IS-IS as PE-CE but it is not usually used between PE-CE in real production environments.
