Is the network between R2 and R4 in the 10.x.x.x/24 address space though?
(it appears at first glance to be 172.31.0.0)
If I recall correctly, it will only use the subnet of the interface IF the
interface is in the same major network.
Thanks
Larry

Subject: ospf - rip redistribution issue.
I am redistributing ospf E2 routes in rip v1. I have no auto-summary enabled
in rip but next hop rip v1 router receive a classful summary route (should
summarized as per mask which is 24 bit).
ospf----R2------rip-------R4
R2 redistributing ospf to rip.
ospf routes are :
10.1.1.1
10.2.2.2
| | | |
10.9.9.9
R4 receive summary that is 10.0.0.0
Mask on R2 interface pointing to R4 is 24 bit.
All ospf routes are Type E2.
