Hi forum,

I have just picked up a JG920A switch for my home lab and am having problems getting inter-vlan routing working on it. To keep things simple I have create two vlans 100 and 200. 100 is untagged on port 1 and 200 is untagged on port two. I have configured SVIs on both vlans (192.168.100.1 and 192.168.200.1), with a client on a network port assigned to to these vlans.. I'm not able to ping between clients and can't even ping the SVIs on the switch diagnostics.

Have a I missed something. I thought that global routing was enabled as soon as an SVI was added?

Hi, creating SVI addresses for your VLANs automatically should enable L3 routing on the Switch.

Say you have configured (configuration saved)/connected:

1. VLAN 100 -> SVI 192.168.100.1 255.255.255.0 (/24 subnet).
2. Client A belonging to VLAN 100 with IP 192.168.100.10 /32 with 192.168.100.1 as its Default Gateway AND connected to an edge port (access mode) untagged in VLAN 100.
3. VLAN 200 -> SVI 192.168.200.1 255.255.255.0 (/24 subnet).
4. Client B belonging to VLAN 200 with IP 192.168.200.10 /32 with 192.168.200.1 as its Default Gateway AND connected to an edge port (access mode) untagged in VLAN 200.

Then Client A and Client B should both be able to ping their respective Default Gateway, the opposite one and ping each others too (provided that each Client's Guest OS Firewall is correctly configured to admit ICMP to pass, eventually try to disable it entirely and repeat your connectivity test).

Are you able to download the running configuration and opening it to see how it is?
