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
