Inter VLAN Issue

mmarie
Level 1
Level 1

Hello

We have new branch and we will connect it through 4G routers "WAN connection" and L3 switches as below Fig.

From 1-Branch Switch i can ping the 2-Branch Switch, but from (PC-1) i cannot ping (2-Branch Switch) also (PC-2).

Maybe i have missed something.

Here is the Routers and Switches conf.

 

1-Router

Gateway of last resort is 0.0.0.0 to network 0.0.0.0

S* 0.0.0.0/0 is directly connected, Tunnel1
10.0.0.0/8 is variably subnetted, 5 subnets, 3 masks
C 10.65.17.0/29 is directly connected, Vlan1
L 10.65.17.2/32 is directly connected, Vlan1
C 10.201.51.0/24 is directly connected, Cellular0
L 10.201.51.1/32 is directly connected, Cellular0
S 10.201.56.24/32 is directly connected, Cellular0
172.20.0.0/16 is variably subnetted, 2 subnets, 2 masks
C 172.20.218.196/30 is directly connected, Tunnel1
L 172.20.218.198/32 is directly connected, Tunnel1

Hi @mmarie ,

 

The routers do not have a route to the VLAN networks (Router 1 to VLAN 26 and Router 2 to VLAN 11).
You can achieve this by configuring a static route or a routing protocol.

 

Regards
