preparing for the ccna, and practiced with a simulator,in this
i have 11 pc's connected to switch 2950 and another 11 pcs connected to switch 1912.
here,
in swicth 2950,
ip address= 10.0.10.50
default-gateway=10.0.10.100
fa0/1,2,3,4=vlan 1 (one)
fa0/5,6,7,8=vlan 2(two)
fa0/9,10,11,12=vlan 3(three); fa0/12 used for trunking, though i did not assign it to vlan 3
, it took it as vlan 3(?)
pc1-11 are assigned ip addresses 10.0.10.1 thro 10.0.10.11
in switch 1912,
ip address= 10.0.20.50
default-gateway=10.0.20.100
e0/1-5=vlan 1(one)
e0/6-8=vlan 2(two)
e0/9-11=vlan 3(three)
and fa0/26 used for trunking
pc12-22 are assigned ip addresses 10.0.20.1 thro 10.0.20.11
ping
pc1 to pc 11 =OK
pc1 to pc17,21 =not pinging (sure as these 2 are in different vlans)
the problem is when i tried to
ping from
pc21 to pc1 =
pings (though it is different vlan), why it is happening?
from all pcs connected to 1912 a ping to other pcs on 2950 whether they are in same vlan or different , the
ping succeeds
similarly when i tried
within the same switch 2950,
from pc1 to pc 6, it
pings
it should not succeed right? as its in differnt vlan
i tried to debug,
with
show int f0/12 switchport, it displayed trunking encapsulation as dotq and while in 1912 as isl,
i thought this may be the cause.
but how to change the encapsulation?
plz someone clarify this
