1. If on R3 eigrp is enabled on loopback 0, then why do you need to redis
connected. Just make sure you have network statement under eigrp
router eigrp 2
net 10.0.0.0
I have to "redistribute connected" for connected isis interfaces that won't
be redistributed with "redistribute isis" under both EIGRP AS's.
2. If both the router R2 and R3 redistribute the AS2 to AS1 then R1 will
get two route and both will external D EX. R1 will select the better metric
router.
3 R2 will be getting this router as internal
This is what I expected, but not what I saw. R2 did have a D entry for this
network from R3 across AS 2. R2 was sending this route to R1, but R3 was
not. Once I added R3's loopback to the ACL for the route-map for
redistributing connected ISIS interfaces into EIGRP 1 and 2, R1 received the
route from R3 and chose R3 as the best path. It still had R2's path in the
topology table.
4. If redistribution ( as2 to as1) is happening only of R3 then R1 get only
one router i.e from R3.

I have simulated and I got two routes in eigrp topo on R1 and it select best
route via 150.50.124.6 (R3) because of better metric.
R1# sh ip ei topo
