Jay and Yong,
When you are doing mutual redistribution between OSPF and RIP, there are
several ways to get the OSPF routes into RIP:
(1) Use RIP version 2
(2) Create a /30 secondary address on the R2-R3 link so R3 will learn the
/24 AND /30 routes (repeat for other masks)
(3) Create a tunnel between R2 and R3 with a /30 mask (repeat for other
masks)
(4) My favorite if you can't use RIPv2: Create another OSPF process on R2;
redistribute OSPF 1 into OSPF 2; add summary-address statements under OSPF
2; redistribute OSPF 1 and OSPF 2 into RIP.
HTH, Kym
