Inter VLAN Layer 2 and Layer 3
I have created a layer 2 VLAN, in order to connect a router interface with a riverbed box wan Interface on a Dell N3024 - The riverbed lan Interface is connected to a layer 3 VLAN on the same switch.
As for now, it is not possible to establish a between these 2 VLAN's
Relevant part of my config:
Layer 2 VLAN
vlan 3
name "RVB-Ports-WAN-0.0-Pri"
interface Gi1/0/1
switchport access vlan 3
exit
interface Gi1/0/2
switchport access vlan 3
exit
Layer 3 VLAN
interface vlan 2
ip address 10.201.35.2 255.255.255.0
interface Gi1/0/3
switchport access vlan 2
Is there a technical limitation causing this problem or is something missing in my configuration?
Thanks

Thanks for revert Daniel. The global command "IP Routing" is already set:
ip routing
ip route 0.0.0.0 0.0.0.0 10.201.35.100
My intention is to separate the LAN interface of the router and WAN interface of riverbed box in a VLAN with pure layer 2 functionality. The LAN interface of the riverbed box should be connected to a VLAN with layer 3 capabilities.
In the past I have used layer 2 switches (Dell PC 3524). On these devices it was possible to separate the WAN and LAN path as described above
If that not works I will be forced to connect the router and riverbed box directly with a Network cable, instead of connect them by using the switch ports. Is this correct?

We have different type of Cisco Routers from our MPLS provider (mainly 2000 series) and different type of Riverbed boxes (250,550,1050). Indeed - I try to segregate the traffic as it enters the network - from the Cisco router LAN interface to Riverbed WAN0.0 (Layer2 VLAN) and from Riverbed LAN0.0 into the LAN (Layer3 VLAN). Let know if you need more details. Thanks
