To not lose the "even-numbered" routes (10.1.12.x and 10.1.14.x) in the OSPF domain, reinstate the original
redistribution in the North router:
router ospf
area backbone
redistribute connected
redistribute rip
exit
And move the prefix list, route map, and redistribution from the North router to the South router. To get the same
distribution of routes from the northern RIP to the southern RIP domain, add the 10.1.15.x and 10.1.16.x routes to
the prefix list—they will not be redistributed by the
redistribute connected
command because they are not
directly connected to the South router. The prefix list would expand to:
ip prefix-list "Odds" seq 5 permit 10.1.11.1 255.255.255.0 ge 24 le 24
ip prefix-list "Odds" seq 10 permit 10.1.13.1 255.255.255.0 ge 24 le 24
ip prefix-list "Odds" seq 15 permit 10.1.15.1 255.255.255.0 ge 24 le 24
ip prefix-list "Odds" seq 20 permit 10.1.16.1 255.255.255.0 ge 24 le 24
The route map would move from North to South with no changes:
