290 | Chapter 11. Virtual Routers
NETGEAR 8800 User Manual
When you add a protocol to a user VR, the software starts a process to support the protocol,
but it does not enable that protocol. After you add a protocol to a user VR, you must
specifically enable and configure that protocol before it starts.
Note: You must add, configure, and enable a protocol for a VR before you
start unicast or multicast forwarding on the VR and before you
configure any features (such as VLANs) to use the VR.
To add a protocol to a VR, use the following command:
configure vr <vr-name> add protocol <protocol-name>
If you add more than the maximum number of protocols, the following message appears:
Error: Maximum number of Protocols that can be started in the system is 48
To remove a protocol from a VR, use the following command:
configure vr <vr-name> delete protocol <protocol-name>
Configuring Ports to Use One or More Virtual Routers
By default, all the user data ports belong to VR-Default and the default VLAN, Default. All
these ports are used exclusively by VR-Default. To configure a port to use one or more virtual
routers, you need to perform one or more of the tasks described in the following sections:
• Deleting Ports from a Virtual Router on page 290
• Adding Ports to a Single Virtual Router on page 291
• Adding Ports to Multiple Virtual Routers on page 291
Deleting Ports from a Virtual Router
To configure a port for exclusive use by another VR, or for use by multiple VRs, it must first be
deleted from VR-Default. You must delete the port from any VLAN it belongs to before
deleting it from a VR.
To delete a port from a VR, use the following command:
configure vr <vr-name> delete ports <portlist>
CAUTION:
Do not create Layer 2 connections between ports assigned to different
VRs in the same switch. Because each switch supports just one MAC
address, every VR in the switch uses the same MAC address. A Layer
2
connection between two VRs can cause external devices to direct traffic to
the wrong VR.
