Hi Cliff,
This should be easy
158.168.1.0 to 158.168.92.0 (you only want even subnets)
158.168.2.0, 158.168.4.0, etc
158.168.00000010.0 ---> 2
158.168.00000100.0 ---> 4
158.168.00000110.0 ---> 6
and so on. So you will need to ensure the 24th bit is zero.
so an access-list like this will work 158.168.0.0 with a mask
00000000.00000000.11111110 .111111111
-> access-list 99 permit 158.168.0.0 0.0.254.255
router eigrp 1
redistribute ospf 1 metrix x x x x x
distribute-list 99 out ospf 1
Will this do the trick?
