Re: how to make Vlans talk to each other on two separate network? Vlan 10 and Vlan 20

Hello,

 

the routing on your routers is incorrect. You have several options:

 

Static default route on both routers:

 

Router2

ip route 0.0.0.0 0.0.0.0 192.170.1.2

 

Router3

ip route 0.0.0.0 0.0.0.0 192.170.1.1

 

or (on both routers):

 

router rip
version 2
network 0.0.0.0

 

or

 

router eigrp 1
network 0.0.0.0

I would not advise the above, Having default routes pointing directly to each other is asking for trouble, If this was on a production site it could cause a lot of issues basically what you are doing here is introducing a routing loop.

If any host from either side trys to reach a network that its local rtr isnt aware of then the rtrs will push it towards their own default nexthop so then they will continually send it to each other thus a loop is created.

 

@jamesidk41403  As for you topology you have the same subnets running on both rtrs which isn't applicable

Using RIP is okay but suggest disable auto summerization  and use version 2 rip and remove the above default routes.

The phones are talking ? You added the dial peers on both sides ?
