i have two vlans configured into a juniper netscreen (a screenOS device). I have connected a catalyst to the nic i have configured the vlans on. I need an example configuration to shoot into the cisco to be able to ping both juniper vlan addresses from the cisco

share|improve this question

the juniper carry two vlans on one physical port, which then the catalyst is connected to?
If so: make sure the port on the catalyst is a trunk port (and then configure another port on the cisco with either of the vlans and try to ping the netscreen from there).

You can simply create an int vlan ip address and ping from the catalyst after the trunk port is configured. – voodooo Jan 26 '11 at 14:00
Given it's a L3. Seems 3550 series are all L3, is that correct? – 3molo Jan 26 '11 at 14:02
