RIP

[vincent.rs]

I have subnetted 192.168.0.0 with subnet mask 255.255.255.240. I am using RIP to advertise two networks 192.168.0.80/28 and 192.168.0.96/28 which are on the same router. When i try "show ip route" on the next connected router it is not receving the updated ip route table.

So i go back tho the previous router and check the config

Current configuration : 711 bytes

Ther in RED. It is advertising 192.168.0.0. Why is it not recognizing the subnet even after it is version 2???

Well this was being done in Cisco Packet Tracer!

Do no auto-summary

HI

First at all you should be sure that the networks that you are announcing in R5 are present in its rounting table. You can do this issuing the command "show ip route" and you should be able to see the two networks 192.168.0.80/28 and 192.168.0.96/28 directly connected. If you don't see one of the networks is because the port associated with the network is down, troubleshoot this problem first. If in fact you see both networks connected in R5's routing table, the next thing you should try is ping next hop  routers, if you can ping the next hop routers I'm sure you will be able to announce the directly connected networks to the surrounding routers.

One thing that you shuold kno about RIPv2 is that RIPv2 perfoms autosummary at the mayor network boundary.
