INE SPV3 rack rental

Hi Brian,

Thanks for Your response.

Im trying to pass the traffic between R4 and R5, with XR just passing traffic
between those. However,there is no AC attached to XR.I got that log earlier
and removed XR attached AC.

My understanding is that limitation comes to the play when I want to pass the
traffic from R5 or R4 to behind the XR. So if I want to pass the traffic
between R5 and R4 , this limitation of Engine 3 line cards still will apply?

Cheers,

Jeremy

When you configured this the XR would have generated a logging message telling
you that the configuration commit was successful, but traffic forwarding won't
work because it's an unsupported config.

The issue is that engine 3 line cards cannot be customer and core facing at
the same time. You need to change the design so the XRs are connected in the
core with the POS link, and then use the GigE for the CE facing attachment
circuits.
