For the 5320 Series, only 5320-48P-8XE and 5320-48T-8XE support more than one VRF with IP configuration.
The 16- and 24-port 5320 Series models support a single active VRF with IP configuration; the VRF can be the Global Routing Table (GRT) or a non-default VRF:
The GRT becomes the active VRF if you attach an IP interface to a VLAN. Otherwise, the first non-default VRF you create becomes the active VRF.
If the GRT is the active VRF, you cannot create a second VRF.
You cannot create more than one non-default VRF.
You cannot configure IP interfaces in the GRT if the active VRF is a non-default VRF.
To transition the active VRF from the GRT to a non-default VRF, remove all IP interfaces and then create the non-default VRF.
To transition the active VRF from a non-default VRF to the GRT, first remove all router, ARP, and IP interfaces. Delete the VRF, and then add IP interfaces to the GRT.
Support for a single active VRF affects other features that rely on VRFs with IP configuration:
Fabric Extend—you must configure a route-map policy to suppress IS-IS redistribution of the FE tunnel subnet:
Configure route-maps to not permit redistribution of the local route used as the tunnel source address (ip-tunnel-source-address command).
Configure an accept policy to deny IS-IS routes that overlap with the destination tunnel IP address.
IP Shortcuts and Layer 3 VSN—You cannot configure the IP source address (ip-source-address command) as an IP address in the GRT if the active VRF is a non-default VRF.
