I am adding a 2nd layer 3 link between data centers using EIGRP. I want the remote sites to continue to use the 100 Mb to routes that are in Data Center 2 (unless the link is down).

If I'm correct the 200 Mb link from data center 1 then across would be a better metric. Can I use the bandwidth command on the Nexus interface to get the result I want?

You can influence EIGRP routing with either the bandwidth or delay commands. In general, the delay command is preferred because the bandwidth command can change other things, e.g. QoS.

  • Bandwidth calculation in EIGRP is actually only concerned with the minimum value in a given path, while delay is additive. Changing the local bandwidth value is meaningless to the calculation if the value is still greater than the slowest link. – rnxrx Mar 17 '17 at 12:24
