Hi
I want to know I can influence routers to use a slower but more reliable path than a faster path in EIGRP. But I would still want the less reliable path available as a backup.
I have the attached topology. I would like R2 and R3 to use the 100Mbps path as opposed to the 1G path between R1 and R2 as this is faster but unreliable. All interfaces have the default 10usec delay. How much delay would I need to add to the interface on the link between R1 and R2 to make it less preferred.
I just want to be sure before I attempt anything so hoping someone can advise
Thanks

Hello Mokhali82,
As you are aware with EIGRP metric calculation minimum bandwidth is set to the minimum for entire path, and it does not reflect how many hops or low bandwidth links are in the path. Delay is a cumulative value which increases by the delay value of each segment in the path.
what is the output of show int 0 and show int 1 in R2 like for example below
R8# show interface ethernet0/1 Ethernet0/1 is up, line protocol is up Hardware is AmdP2, address is 0050.7329.52e1 (bia 0050.7329.52e1) Internet address is 10.1.43.3/24 MTU 1500 bytes, BW 10000 Kbit, DLY 1000 usec,
which can show you the delay parameter on that interfaces based on that you can add 110 or 120 more delay vlaue between R1 and R2 link to make it less preferable.
Hope it Helps..
