When redistributing a route learned using iBGP to EIGRP, the route is not advertised.
※ios behavior
[Topology]
dev2 and dev3 is configured with iBGP of AS 64512.
dev3,4 and dev5 is configured with EIGRP of AS 1.
In dev3's EIGRP AS 1 settings, routes learned with iBGP AS 64512 are redistributed.

Expected Behavior
The expected behavior is that iBGP learned routes are advertised as EIGRP routes in the dev4 route information.

However, when I run batfish (bfq.routes()), I see that the iBGP routes that should exist on dev4 are not learned by EIGRP.
