[c-nsp] EIGRP route knob tuning

[Matthew Huff]

Anyone know what Cisco's plans for the metrics in EIGRP? 10GE has the bandwidth set at max and the delay set to minimum, so how are they going to handle 40GB and 100GB? Is there any whitepapers posted?

I ran into this a while looking at our core routing. The SVI on a 6500 is set to a bandwidth equal to a gig-e interface, so we had some inefficient routing given that we had 10GE layer 3 connections to our distribution. Some routes were heading to the distribution and back rather than across the Layer 2 trunk because the Layer 2 trunk SVI had lower bandwidth. Adjusting the SVI to the max (same as a 10GB interface) fixed the problem. What happens when 100GB uplinks appear?
