The ospf domain uses subnets of 10.0.0.0
The eigrp domain uses subnets of 20.0.0.0
The route in question was 10.1.0.0/16
As I said, all is good now that I have sung and danced and done the hokey
pokey. I am just curious if there is a rational explanation - something I am
overlooking. I cannot think of one.
Now it looks like this:
O IA 10.3.0.0/16 [110/138] via 20.253.253.5, 09:35:13, Serial1
O IA 10.1.0.0/16 [110/74] via 20.253.253.5, 09:35:13, Serial1
O IA 10.202.0.0/20 [110/138] via 20.253.253.5, 09:35:13, Serial1
Before it looked like this:
O IA 10.3.0.0/16 [110/138] via 20.253.253.5, 09:35:13, Serial1
D EX 10.1.0.0/16 [170/26137600] via 20.253.253.1, 00:06:11, Serial1
O IA 10.202.0.0/20 [110/138] via 20.253.253.5, 09:35:13, Serial1
( note - I did some cutting and pasting to duplicate the appearance. With
the problem gone, I do not have traces to show. )

What prefixs' are you using on the OSPF and EIGRP sides?
