Hello Professionals,
Device: SG300-28MP 28-port Gigabit Max-PoE Managed Switch
Firmware: 1.4.11.5
I have added VLAN 10 and 20 with 192.168.[VLAN].254 /24 with access ports for VLAN 10: GE1, GE2 and VLAN 20: GE20
Also I have added two trunk ports GE25 and GE26 allowed VLANs both 10,20
GE25 IP: 192.168.254.254 with uplink IP 192.168.254.253 /24
GE26 IP: 192.168.178.254 with uplink IP 192.168.178.1 /24
The GE25/26 are for testing two devices and figure out, the problem is on that side and not the Cisco itself.
If I ping the uplinks IP out of the Web-Based Management Interface it works if I select "Auto" but if I select one of the VLANs it doesn't work. Doing the ping from a client connected to GE20 with default GW 192.168.20.254 (the VLAN Interface) I can ping other VLAN Interface like 192.168.10.254 and also the trunks IP 192.168.254.254 but neither the uplink nor later hops. Pinging the uplinks IPs from the uplink-routers works (there is a working route back).
The goal: Clients at ports of VLAN 10,20 should ping and access the internet through the uplinks.

The bridge multicast stuff is from clicking around within the GUI ... sorry.
Maybe the best way to help is to send a minimalistic running-config I can use to test with my basic setup.
(adding VLANs & Interfaces and also default-route or default-network)
I noticed my device cannot do OSPF .. and I got response iOS doesn't know the command ip routing or default-network which I should enter as described in a tutorial. Maybe there is a basic problem ? Hope someone can see my mistake - I am confused at the moment.
In my understanding I have to use default-network instead of static routes with default-route if I use VLANs with IPs for their Interfaces. But I cannot enter the corresponding commands.
My greatest wish would be a working config I simple can test with my minimalistic setup. But also hints are welcome
Thanks for your time

Solved myself: Routing back was not done in both of the routers.
