We have an issue with inter-vlan routing let me explain what we have.
We have 5 vlans:
- vlan 1
- vlan 101
- vlan 111
- vlan 121
- vlan 131
The main core switch is the 1920S and connected to this is x4 1820.
When on on vlan 121 I am not able to ping anything on vlan 101 which is essential.
Strangely though, when on vlan 111 I can ping devices on vlan 101, the config is no different.
A tracert from a device on vlan 121 to vlan 101 stops at the 1920S core switch.
Here is the running config on the 1920S:
!Current Configuration:
