You can See L3 routing on Core 1,

So if you ping the server from host behind catalyst wih normal size it works
fine and reply

but if you ping with size of larger than 1450, it will timed out.

Now when I show my mac-address-table on core 1, there is no mac
1111.1111.1111 (132.16.66.6) appear on my CORE 1 CAM, but when I ping it
132.16.66.6 from my core 1, it MAC appear 1111.1111.1111 via Port-channel 1.

When it appear, I can ping the server 192.168.1.1 with size of anything
(above 1450), it will reply. But 40 seconds later the CAM Automatically
disappear and it wil timed out again the ping packet to the server which is
it size above 1450.

I wonder if anyone have ever face this kind of problem ? Can anyone give me
explanation why this is happen ? Is it a IOS Bug ?

This is really CCIE Test for me and everybody in my country :)
