Hi Luke,
Here is the config:
1912: #ip addr 10.1.1.2 255.255.255.0
#ip default-gateway 10.1.1.1
2620: #int f0/0
#no ip addr
#exit
#int f0/0.10
#encap isl 10
#ip addr 10.1.1.1 255.255.255.0
#shut
#no shut
#int f0/0.20
#encap isl 20
#ip addr 20.1.1.1 255.255.255.0
#shut
#no shut
#end
And so on for 30.1.1.1, 40.1.1.1.......till 80.1.1.1
1st pc ip=10.1.1.10, 255.255.255.0, 10.1.1.1
2nd pc ip=20.1.1.10, 255.255.255.0, 20.1.1.1
And so on till 80.1.1.10, 255.255.255.0, 80.1.1.1
All the pc's are plugged into the 1912. The router is plugged into f0/26.
All pc's can ping one another and the router and ditto from the router back
to each pc. Same for telnet from a pc to the router. NO problem.
*** But CANNOT ping the switch from the pc or the router no can ping the
swich ip on the switch itself or the router or any pc *** This is the
problem.
Please advise.
Thank you.
