I have not been able to figure this one out either. Very frustrating.

If you do find an answer, please post to the list.

Subject: [j-nsp] MX/Trio, mirror IRB egress traffic with VLANs
Message-ID: <[email protected]>
Content-Type: text/plain; charset=us-ascii

Hey,

Consider traffic flow:
MPLS_core => irb => virtual-switch => IFL

As far as I can see, there is no way to mirror this traffic with VLAN headers
intact?
 a) irb output filter sees traffic, but not VLAN
 b) virtual-switch forwarding-options filter input does not see IRB traffic
 c) IFL family bridge filter output does not see IRB traffic

Any solution to this problem?

However the other direction:
IFL > virtual-switch -> irb -> MPLS_core
 a) IFL can mirror traffic with VLAN
 b) virtual-switch forwarding-options filter input sees traffic with VLAN
 c) IFL irb input won't see (expectedly) VLANs
