Hi folks,

Where are the “VRF specific” forwarding-filters executed please?

In a setup like this:
set routing-instances TEST_VRF forwarding-options family inet filter input TEST_FW_IN

WAN-W—PFE-W--Fabric—PFE-E—WAN-E
PFE-West hosts an MPLS interface
PFE-East hosts a TEST_VRF interface

Fact:
East to West as well as West to East traffic is subject to the forwarding-filter

A)
Is the West to East as well as East to West filtering be done on PFE-East?
B)
Is the West to East filtering done on PFE-West
And East to West filtering be done on PFE-East?

Note:
If the filter is applied as input filter to the VRF, then filter is applied before route lookup
And output filter at the VRF level would mean filtering is done after route lookup
