Router Breakout switch port configuration template:

( Routers R1 – R6, connected to ports 1 to 12)

interface FastEthernet1/0/1

 switchport access vlan 11

 switchport mode dot1q-tunnel

 l2protocol-tunnel cdp

 l2protocol-tunnel stp

 l2protocol-tunnel vtp

 no cdp enable

( Switches SW1 – SW4, connected to ports 31 to 34)

interface FastEthernet1/0/32

 switchport access vlan 402

 switchport mode dot1q-tunnel

 l2protocol-tunnel cdp

 l2protocol-tunnel stp

 l2protocol-tunnel vtp

 no cdp enable

(GNS3 Workstation eth0)

interface FastEthernet1/0/48

 switchport trunk encapsulation dot1q

 switchport mode trunk

 l2protocol-tunnel cdp

 l2protocol-tunnel stp

 l2protocol-tunnel vtp

 spanning-tree portfast

 

NOTE:

In my GNS3 workstation, the sub interfaces connected to gns3 routers R1 to R6 are gone after a restart. Hence before opening my project I have to issue the following commands in the terminal with root privilege or super user as I run “sudo su” and type all commands below:

 modprobe 8021q

vconfig add eth0 11

vconfig add eth0 12

vconfig add eth0 13

vconfig add eth0 14

vconfig add eth0 15

vconfig add eth0 16

vconfig add eth0 17

vconfig add eth0 18

vconfig add eth0 19

vconfig add eth0 20

vconfig add eth0 21

vconfig add eth0 22
