Hi
I'm having a problem with my vlan configuration.
I've set up a number of VLANs on my router and coresponding sub interfaces on g0/0. On g0/1 I've set an IP address and have this connected to a switch with no VLANS set up on as its just dealing with the devices on the same IP scheme. On another switch I have a port set up for one of my VLANs and a trunk port. I have this connected to g0/0 i.e. the subinterfaces port.
I can ping the g0/1 ip address and subinterface addresses from either switch however I cannot ping a device on a VLAN from a VLAN.
Any idea what I'm doing wrong, its fairly simple in theory but complicated in practice!
My router is a 2921 and one switch is a 2950.
