configure vlans on router - not as simple as I thought
Router R1 is connected to router R2 via their fa0/0. The question asks "R1 and R2’s F0/0 interface should be configured in VLAN 12" (I quote here from the question)
I thought this was a simple step but...
1. using sub-interface
encapsulation dot1q 12
ip add x.x.x.x 255.255.255.0
using subinterface seemed fine for vlan and eirgp protocol. However, in the next steps of the question, it asks using leak-map option in "ip summary-addrress eirgp ..." command. The leak-map option only works on physical interface NOT sub-interface. So there is a conflict here.
2. I tried to use "switchport" command on fa0/0
After entering fa0/0 interface mode, I found out that I could NOT enter "switchport" command. There was no such command available!!
Switchport command makes the interface into a layer 2 interface. However the question clearly asks to configure IP address on the fa0/0 interface
I use GNS3 with 3600 Software (C3640-IK9O3S-M), Version 12.4(13b)
What did I miss? I am confused. What is the appropriate way to finish this task?
