[j-nsp] PBR needs to be applied on tunnel interface (st0)

Hi,

The good old trick of a loop link could do it.
You could use logical tunnel, or pair of spare physical port with a hairpin/loop cable.

Place st0 and one end of loop in own instance, routes either to st0 or loop as appropriate.
Then apply PBR to other end of the loop.

Search the archive for recent discussion on using lt interface.

Cheers,
