Hi all... im struggeling with a setup at home which makes me crazy..
i have 1 router 2651 and 2 2950 switches.
the setup is like a router on a stick.
i use 3 vlans 10 ( native) 20 and 200.
vlan 10 is only used for management and no clients are connected.
on switch 1 i have connected 2 pc's 1 in vlan20 and 1 in vlan200.
on switch 2 i have the same........
Pc in vlan20 on switch1 can communicate with pc in vlan20 on switch2.
Pc's in vlan200 can also communicate.
pc in vlan20 on switch1 can cummunicate with pc in vlan200 on switch1 .. but cannot communicate with pc in vlan200 on switch2
However the pc in vlan20 on switch2 can communicate with pc in vlan200 on switch1.
Can you follow !?
so the main question is why is it impossible to communicate with the pc in vlan200 on switch2 from pc in vlan20 on switch1 ???
