Traceroute on EIGRP

[jimfixit]

What would I expect to see if I traceroute from a server to a point that has two equal weighted eigrp paths?

What I'm seeing is each hop appears to be bouncing back and forth before moving to the next hop. At first I thought, "well traceroute does 3 pings to each hop then moves to the next one, maybe this is what load balancing looks like"....but I'm not so sure.

Like, I have router A connected to Router 1 and Router 2. They are connected to frame relay, then to Router 3 and 4. Router 3 and 4 connect to Router B.

Router A shows two routes to Router B, one through router 1 and another through Router 2. When I ping from router A to B, this is what I'm seeing:

1 10.1.1.22 ... (lan int on router 1)
10.1.1.33 ... (lan int on router 2)
10.1.1.22 ... (lan int on router 1)
2 68.1.1.3 ... (wan int on router 2)
68.1.1.2 ... (wan int on router 1)
68.1.1.2 ... (wan int on router 2)
3 10.32.1.1

10.32.1.1 being the point on Router B I'm hitting.

So...should I be seeing that? It seems to me like it's bouncing in a loop before it gets to router b....

Looks like a atypical traceroute with more than 1 path.

Hello
This is Eigrp do it's per packet load balancing.When it find equal paths it's justload balance without asking anyone.

ah thank you, I was afraid I'd lost my mind. SO....that would mean that if I set up PBR to where there is one prefered route, that should mean I would see only the one path, not this LB output. Cool...I have a valid testing mechanism!

Thanks folks!
