Interesting nothing is being counted in the reverse direction from rtrB
back to rtrA, can you confirm unidirectional ICMP with "debug ip icmp"
on one of the targets?

What IOS versions are you running on both of these? I can see a
difference in the output (tag switching vs label switching) here.

Dave.
