Group,
I think I know the answer to this one, but I would like to be sure. The
example topology is as follows:
________
Host A ----R1_______ R2------ Host B
R1 and R2 are doing load balancing OSPF, EIGRP, whatever its not important.
Host A pings Host B and the trace that comes back should not be exactly linear
correct? Load balancing would cause some packets to take route 1 vs. route 2.
(round robin)
I have a similar situation in my home lab and want to make sure what I'm
seeing is actual the result of load balancing.
The traces look something like this when I have load balancing enabled.
Tracing the route to 111.1.1.1
1 160.1.1.6 4 msec
150.1.1.2 0 msec
160.1.1.6 0 msec
2 141.1.1.5 32 msec
141.1.1.9 36 msec
141.1.1.5 36 msec
3 171.1.1.3 36 msec 36 msec 32 msec
4 180.1.1.8 36 msec
And when only one link is available the trace looks like this:
Tracing the route to 111.1.1.1
1 160.1.1.6 0 msec 4 msec 4 msec
2 141.1.1.9 28 msec 32 msec 36 msec
3 171.1.1.3 32 msec 36 msec 32 msec
4 180.1.1.8 36 msec * 32 msec
All ping attempts are successful and no data is ever lost. I'd just like to
verify that traceroute is actually displaying load balancing.
