[f-nsp] Asymmetrical routing on ADX

[Drew Weaver]

That's exactly my stance on this issue.

It's especially annoying considering that the two physical ports in question are attached to a VLAN/Virtual Ethernet, I don't understand why it matters which physical interface in the VLAN handles the traffic destined for the VE..

To me that is really broken.

Thanks,
-Drew

It isn't (even without a complete mesh).

Asymmetric routing is commonplace and normal, if you need a chokepoint to apply some sort of network policy (load balancing, firewalling, etc.) you need to make sure that you make it a chokepoint both coming and going, and if gear can't handle the next-hop (or even the interface that it uses) may be different for transmitted and received traffic, then bug reports need to be filed.
