ripv2 / routing table

jamesleecoleman

Hey

I'm still alittle confused on rip and the routing table.

I read that for ripv2 to work, I have to type the network number corresponding to the interface. The information will go out that interface. I thought it would go all interfaces. Now for example.....

router1
fa0/0 ip address 192.168.1.1/24
s0/0 ip address 192.168.10.1/30

router 2
fa0/1 ip address 192.168.2.1/24
s0/1 ip addresss 192.168.10.2/30

connected by serial cable

If I just set up the ripv2 information for fa0/0 for router1, would it go out the s0/0 interface because the s0/0 has the network number in the routing table as connected? Or will I have to include that s0/0 number in the ripv2 configuration so the other router will know the network number?

I'm confused because in packet tracer, I have to put the ethernet and the serial network numbers in there to make ripv2 work. If i take out the serial network number, it'll still work.

For RIP think of the command R1(Config-router)# network network_number
where network_number are those networks on your router which you would like to be advertised in via RIP protocol.

In your scenario lets say if you only do network 192.168.10.0 for R1. R1 will only advertise 192.168.10.0 network in its RIP packets to R2.

If you do network 192.168.2.0 and network 192.168.10.0 for R2 then R2 will advertise both its connected n/w in RIP to R1 . However when you will try to ping from a host in 192.168.1.0 network to a host in 192.168.2.0 or host 192.168.10.2 [Serial interface of R2]the ping will be unsuccessful as R2 will not have route back to network 192.168.1.0 in tis routing table.
