Route issue in this lab setup

whiteford

Hi, I have 3 routers set up in this lab (see diag), the LAN at the bottom can ping router R3-2610's ethernet port at the top, but not the SE0/0 port. Now R0-2610 and R1-2610 are using RIPv2 and I have not added any dynamic routing to R3 yet, what would I need to do regarding RIPv2 in this one?

Would I just setup RIPv2 again and will R0-2610 then receive this so my LAN can ping SE0/0 on the R3-2610?

Where is your serial0/0 of R3 is connected ?

Is it up ?

You need to run dynamic routing on R3 to make netwoks , (if any connected ) beyond R3 , reachble from your LAN in the bottom.

So run RIPv2 on R3 also,and advertise the networks connected to it.

Hello Andy,

>> Would I just setup RIPv2 again and will R0-2610 then receive this so my LAN can ping SE0/0 on the R3-2610?

yes, you can do in this way follow the instructions of the previous post and do it also on R3, take care if needed to have a network command matching the R3-R1 lan IP subnet on R1 too.

as an alternate way to do this:

- have R1 advertise R3-R1 lan ip subnet

have on R3

ip route 0.0.0.0 0.0.0.0 R1.lanR3-R1.ipaddress

Hope to help

Giuseppe

Yeah, that is my worry as R3's E0/0 is on 10.10.10.x and R1's E0/0 is on 10.10.10.x too so will this confuse the RIPv2 that's advertising?

Then again is it possible to put R3 E0/0 into it's own VLAN on the switch and then use a different IP?
