Hi,
I've got this topo:
CE1 --- Hu0/0/0/8<vrf>(local NCS)Hu0/0/0/6 --- (P nodes) --- (remote NCS)vrf --- CE2 (10.242.0.0/16)
# end.dt4 is used.
The problem is the local NCS doesn't forward traffic from CE1 to P.
As far as I checked, CEF of vrf and P side is fine.
May I ask what I'm missing?
Here's Remote PE's info:
///

2400:2020:2:4b:42:: is propagated via RR.
This is local PE's info:
In CEF and RIB of vrf side is ok.

Then the Dst (Full SID) is reachable:

But the mystery is why the traffic is not going through to the remote PE.
As far as I checked by monitor command, this local PE doesn't process.

Any comment would be highly appreciated.
