To use a port in multiple VRs, do not add the port to a VR as described in the previous section.
To add the port to a VLAN in the desired VR, use the following command:
Note
See QoS for details about how multiple VRs per port can affect DiffServ and code replacement.
You should configure any protocols you want to use on a user VR before you add a VLAN to the user VR. When IP multicast forwarding will be supported on a user VR, add the PIM protocol before you enable IP multicast forwarding.
The following example demonstrates how to add port 3:5 to user VRs VR-green and VR-blue.
The tagged VLAN bldg_200 was previously configured in VR-green, and the tagged VLAN bldg_300 was previously configured in VR-blue.
configure vlan default delete ports 3:5 configure vr vr-default delete ports 3:5 configure vlan bldg_200 add ports 3:5 tagged configure vlan bldg_300 add ports 3:5 tagged
