[Testbed-admins] How to set up 'Layer 3 switching' in Cisco switch?

["Cheng Cui" <ccui1@tigers.lsu.edu>]

Hello,

I am configuring one of our Cisco 3560E switch as the Emulab control
switch (non-routable control network version). We do not use VTP. As we
are following the divided network designed by Utah, we made the vlans in
control switch as follows:

# Complete (overall):		192.168.0/22
# "public" segment:		192.168.3/24		--ops
# "private" segment:		192.168.2/24		--boss
# "node control segment:	192.168.0/23 
# (aka: 192.168.0/24		--IP controllable devices, e.g. power
controller, switch IP interfaces as well as a second interface on the
boss node (control router's ip: 192.168.0.1)
# 192.168.1/24)	--control net of all experimental nodes

#
# The node control network segment. In vlan 2
#
CONTROL_ROUTER_IP=192.168.0.1
CONTROL_NETWORK=192.168.0.0
CONTROL_NETMASK=255.255.254.0

#
# The private network segment. In vlan 3
#
PRIVATE_NETWORK=192.168.2.0
PRIVATE_ROUTER=192.168.2.1
PRIVATE_NETMASK=255.255.255.0

#
# The public network segment. In vlan 4
#
PUBLIC_NETWORK=192.168.3.0
PUBLIC_ROUTER=192.168.3.1
PUBLIC_NETMASK=255.255.255.0

However, I could not make the inter-vlan (aka: layer 3 switching)
routing successfully. For example, I can't ping ops from boss, reverse
way neither. I have looked at your Utah Emulab topology and I did not
see any real router exists. Can you tell me how you implemented layer 3
switching? How do you assign the Default Gateway in control switch?

Please correct me if I made any mistakes. Thanks.
