I think when I did this I changed the following:
- Set the delay from R4 -> R5 to 2
- Set the delay from R4 -> R1 to 1
- Set the delay from R1 -> R5 to 1
- Set variance to 4 on R4
This way its only the bandwidth that comes into play. So then you just set
the minimum bandwidth on the R4/R5 path to be 4 times that of the other path
(ie 512/128). Just make sure that the bandwidth value you used to inject
those RIP routes into eigrp is equal to or higher than the bandwidth value
of the Ethernet path between R4 and R5.
