Hello Alejandro,
You need to add metric value to your classfull routing process with
which they will be redistributed from classless process.
So. There are two ways doing it properly.
1) Use 'default-metric ...'
2) Use 'metric' parameter for 'redistribute' command
for instance:
router rip
redistribute ospf 1 metric 5
OR
router igrp
default-metric 10 100 255 1 1500
redistribute ospf 1
AC> Hi,
AC> I have two routers connected through a serial interface, I call them
AC> 1750LAB and 3600
AC> The 1750LAB is running OSPF and RIP, it has many routes learned from
AC> other OSPF routers and even external routes from other ASBR.
AC> Well between 1750LAB and 3600 I configured RIP, v1. they share a subnet
AC> from 172.16.0.0, 172.16.36.0/24.
AC> I expected that 3600 would receive routes to all subnets from the same
AC> mayor network with mask 24, but the 1750 LAB only send in the RIP updates
AC> those networks directly connected to it or from the other router which is
AC> connected to it through a subnet with a mask 24. anybody knows why?
