Hi Tim,
The Cisco recommended way to change the metrics for the two links is to
alter the delay on one of them. I am guessing that both of your links
between R3 and R2 have the same delay. Increase the delay on the 1mb link on
R3's side, and then you should see the metric change. If you are running the
default eigrp config, then its only bandwidth and delay for the computation.
If you enable all of the k-values, then its possible that the metrics would
already be different, as then load, reliability and mtu are included in the
metrics.
HTH,
Brian

Subject: Eigrp unequal load balancing problem
Hi guys,
Here's the scenario:
2 mbps
R1 -----64k ----- R2 ========= R3
1 mbps
All routers are running Eigrp. R2 and R3 have unequal load balancing
configured.
Traffic between R2's lo0 and R3's lo0 unequal load balances perfectly.
However, traffic between R1's lo0 and R3's lo0 don't
unequal load balance. In this case, traffic is balanced equally across the 2
links between R2 and R3.
The reason for this is that from R3's point of view, the 2 paths to R1 have
an
equal cost, not an unequal cost because the metric Eigrp uses is based on
the
minimum bandwidth link from source to destination which in this case is the
64k link between R2 and R1.
Is it possible to reconfigure the network so that R3 sees the 2 paths to R1
as
having different costs?
And, if so, how can that be done?
TIA, Tim
