Somewhere during a lab, you bound to have problem. Think of it this way.
Would you really like to add more complexity to your lab test more than is
necessary. I prefer to keep it simple, so I don't have to scratch my head
when problem come up later on. But I guess yeah, it doesn't matter as long
as it can established a session. Not sure the proctor would agree
though..........

Hey, Group.

I had a question about asymmetric routing. Here's a simple diagram:

If a requirement states that R1 must send all packets to R3 via R2, is it
safe to assume that the traffic has to come back from R3 the same way? Is
this the case even if it is not explicitly stated in the requirement that
it
must? Would it be ok if the return traffic came back via R4? I know this
is probably not best practice, but for a lab, would it matter? I'm
thinking
traffic should be sent and returned the most optimal way, but in this
case,
the paths from R3 to R1 have the same metric.

Thanks,
Danny
