best practices on layer 3 routing

[zappo0305]

Please see diagram for exlpaination.

I need to setup a test enviroment where servers in vlan 10,20,30,40 and 50 need to talk to each other, obviously inter vlan routing have to be achieved.

But if I connect the test switch to production switch, what are the best practices should I implement on the switches so the servers on the test vlans will not impact the production switch/network.

Thank you in advance

Hello Tony,

if you have defined manually the list of permtted vlans (98,99 according to your network diagram) on both sides of the link between the switches and you are not running any type of dynamic routing between the devices over associated SVIs you should be fine.

As an additional safety measure you could use VRF lite to put SVIs vlan 10,20,30 and so on on a separate routing table and so that there is no chance of unwanted communication with production network

I would recommend this step

Hope to help

Would you recommend configure vrf on the PE (prod switch)

or on the CE ( test switch)?
