Jay,
Thanks,
Ethernet0 172.50.50.2/24
Serial0 172.60.60.2/24
Serial interface participate in EIGRP routing process thru network command,
Ethernet is not. sh ip eigrp int shows only the serial interface. I did not
put network statement for 172,50.50 network, but is redistributed to EIGRP
using redistribute connected command. So its distance is 170, thus other
routers choose ospf route to the 172.50.50.0 network. As you correctly said
if I use distance 90 90 OR distance 90 100, It solves the problem but it
changes the distance for all the external routes.
Regards,
Ravi
