Hi,

I have a problem with redistribution from OSPF into RIP.
Here's the topology

R1---RIP---R2---OSPF AREA0---R3---OSPF AREA 10

Network between R1 and R2 : 133.7.23.0/24
Network between R2 and R3 : 133.7.147.0/24

On R3, the following loopback interfaces are configured (these loopback are redistributed into the OSPF process) :
loop 1 : 160.100.100.1/24
loop 2 : 160.100.128.1/24
loop 3 : 192.190.100.1/24
loop 4 : 192.190.101.1/24
loop 5 : 192.190.102.1/24

I would like that loop 1 and 2 appears as a single route.
The same for loopback 3,4 and 5.

On R3, I use the following command to create the summary route
summary-address 192.190.0.0 255.255.0.0
summary-address 160.100.0.0 255.255.0.0

These summary appears, as expected, on R2.
Now, I redistribute OSPF into RIP on R2.

On R1, I can only see the 160.100.0.0/16 route !
Why I cannot see the 192.190.0.0/16 route ?

It is because the redistributed route has not it's normal subnet mask /24 ??

Thanks for your help.
