hi guys i am really stucked at vlan.let me tell u my scenario.
i am having switcha and switchb connected to one another and the trunking is enabled.on switcha one machine is connected which is a member of vlan2 and its ip is 192.10.10.2 mask 255.255.255.0 gateway 192.10.10.1.
similarly switchb is having one machine connected which is a member of vlan3 and its ip is 192.10.20.2 mask 255.255.255.0 gateway 192.10.20.1
i have given a ip address on the switcha as 192.10.30.2 mask 255.255.255.0 gateway 192.10.30.1 with appropriate commands.similarly ip address on switchb is 192.10.30.3 mask 255.255.255.0 gateway 192.10.30.1.
my switchb is also connected to a router of 2600 series on its fast ethernet port.trunking is enabled between router and switchb also.
i have created subinterface under fastethernet on router as
int fe0/0.1 ip address 192.10.10.1 255.255.255.0 enacap isl 2
int fe0/0.2 ip address 192.10.20.1 255.255.255.0 enacap isl 3
int fe0/0.3 ip address 192.10.30.1 255.255.255.0 enacap isl 1
int fe0/0 no shutdown.
my switches are having their ip in vlan 1 as seen above.now from switcha i can ping everything.my intervlanrouting is also working.i can ping machine in vlan 3,i can ping all the subif on routers,i can ping switchb also which is vlan1 but i cannot ping the machine which is connected to my switch and which is a memeber of vlan2.i dont know y ????.from the same machine i can ping all the other machine which is in vlan2 and also all subinterfaces on routers.can any 1 tell me y ??
i have done this practical on router simulator of boson.

So in summary if I understand everything correctly
PC's in VLAN 3 and 1 can ping everything
PC in vlan 2 cannot ping PC in VLAN 1 and 3 even though it has a default gateway set to 192.10.10.1 but that same machine can ping the router interface for Vlan 1 and 3 ip of 192.10.30.1 and 20.1.
If the PC is VLAN 2 can ping the router interface on VLAN 1 and 3 then routing is working.
Is this real hardware or a simulator. If simulator may be a bug.
Do you have access list on VLAN 1 or 3 denying ICMP requests
