Routes redistributed from BGP to EIGRP (Can they be redistributed as 90?)

I have a situation where routes are learned by BGP on a router1, router1

redistributes them into eigrp (as distance 170 external ), and sends them to router 2 via eigrp 170.

router2 redistributes those same routes into rip (i know it's a mess), and router 2 sends them rip to router 3 via router2's interface 1, router 3 sends them back to router2 via rip on router2's interface 2, and now router2 is getting a route to the subnet via router3 (120), which it prefers over the 170 which it originally got from router1. (Classic routing loop)

I know how to work around this with access lists , (we actually worked around it with static routes from router1 to the subnets, which it redistributes as 90's into EIGRP ), but my only question is:

Isn't there a way to tell router 2 to treat the 170's that it's receiving from router 1 as 90's, or to tell router 1 to redistribute from BGP into EIGRP, and send the

redistributed eigrp update's out as 90's?

(Static routes are preventing us from doing link backup).

Thanks !

Looks like you can benefit from distance:

For EIGRP process: distance eigrp 90 90

Will result in uniform AD for all routes.

Thanks.

That sounds like the solution.

One question, Is distance only on the receiving end, or will the router

that has the distance 90 90 command configured, also send those 170's

that it received and now converted to 90's internally , out to it's other neighbors as 90's?

No it will only have local significance.
