Hi all ,
    I have tried to make it works , but it is not working .Dynamips config
is same as above in my first mail.i have changed my 3560 breakout switch
configuration to :

*Access Ports Connected to 3560:*

interface FastEthernet0/1
 switchport access vlan 101
 l2protocol-tunnel cdp
 no cdp enable
 spanning-tree portfast

*Trunk Port Connected to Dynamips:*
interface FastEthernet0/15
 switchport trunk encapsulation dot1q
 switchport mode trunk
 l2protocol-tunnel cdp
 no cdp enable

All the Vlans are there in the Breakout switch Vlan Database. When i am
changing the switchport mode (in the Trunk port of the Breakout SW) it is
negotiating with the Dynamips server trunk port. So hope Dynamips Server's
port is working properly as Trunk.

If i enable the Breakout SW fa 0/15 as normal trunk port it can see all the
Dynamips Routers through CDP. but the Dynamips Routers cannot see any of the
out side real devices and failing to lean the mac of the outside devices
through ARP.

Can anyone help me find the issue with this....Do i want to change the MTU
of Server NIC and Switch ?

Regards,
Anbu
