[c-nsp] ip load-sharing per-packet and RPF

[Marr, Joe]

Sure,

I'm a little dense today.

I have 2 AT&T T1s going to the same pop router; they have static's
pointing to the serial interfaces (which are on the same router on my
side)and I have 2 defaults pointing to my serials back to them. 

Based on the util. graphs, the look almost mirrored (and yes, they are
reading different snmp interface IDs).

I've never used CEF to control my traffic in this manner before, so
maybe it's my lack of understanding.

So it could be asymmetrical, but I had thought that that using the "ip
load-sharing per-packet" resolved some if not all of that.

Is the load sharing doing roundrobin or something. If that's the case
then why does several Cisco resources say that RPF supports per-packet
load sharing.

I think it's because your network  has asymmetrical routing (2T1 and
load 
balanced?)
