Here is our situation:
- We use EIGRP in our WAN
- We have customers that connect to us via private line, but we do not control their router (and thus cannot make them peer with us via EIGRP)
- Currently we have a static route to them which we redistribute so that our other WAN sites can connect to them
- My question is:
We have implemented a backup site so our customer now has two routers (one at primary and one at DR). Both are T1s. Do I just redistribute the static route from the DR site as well? The primary site and DR site are connected via 100mb WAN link. For our WAN sites where we control both sides I set delay to be sure our primary site is preferred. But in this case where we don't control the other side, how can I set preference?
While it is a best practice that the delay should be the same on both ends of the link, that is not a requirement. Try setting it on your end and see what result it has. If it does not achieve what you want you can always use the manual control of configuring the metrics in the redistribute of the backup routes.
