Guys anyone seen this before, where "POS interface is not letting Labeled traffic pass through".
I am testing in INE Lab with 3.9.1 IOS-XR Version on Full Scale Lab 4
Basic setup is:
* R3-XR1-XR2, XR1-XR2 are in AS 1000 and R3 is in AS 3000
* R3 has eBGP + Label (send-label) with XR1, also XR1 has /32 static route to R3
* XR1 and XR2 are running IBGP + Label (labeled-unicast)
