Netgear XCM8806 - 8800 SERIES 6-SLOT CHASSIS SWITCH ユーザーズマニュアル

because these three names are the names for the system VRs in XCM8800 releases before 
11.0.

If you exceed the maximum number of VRs supported on your platform, a message similar to 
the following appears:

Error: Maximum number of User VRs supported by the system is 64

To display the virtual routers, use the following command:

show virtual-router {<vr-name>}

To delete a user VR, use the following command:

delete virtual-router <vr-name>

Before you delete a VR, you must delete all VLANs created in that VR. All of the ports 
assigned to this VR are deleted and made available to assign to other VRs. Any routing 
protocol that is running on the VR is shut down and deleted gracefully. 

Changing the VR Context

To simplify VR configuration, the XCM8800 software supports a VR configuration domain or 
context, which allows you to enter commands without specifying a VR in each command. VR 
commands are applied to the current VR context. The VR commands consist of all the BGP, 
OSPF, PIM, and RIP commands, as well as the 

create vlan

 and 

delete vlan

 commands. 

Other commands apply to the switch as a whole.

To enter a VR context, use the following command:

virtual-router {<vr-name>}

Use the 

virtual-router

 command with no VR name, or use the name VR-Default to return to 

the default configuration domain. 

The following example sets the VR context to the user VR helix:

* XCM8806.13 # virtual-router helix

* (vr helix) XCM8806.14 #

The CLI prompt displays the VR context. 

Adding and Deleting Routing Protocols

When a user VR is created, no resources are allocated for routing protocols. You must add 
the routing protocols needed for your VR before you attempt to configure them. 

The maximum number of protocols supported is 48. 

The basic 7 protocols on VR-Default (RIP, OSPF, BGP, PIM, OSPFv3, and RIPNG)

41 additional protocols for user VRs. Any combination of the 5 basic protocols supported 

on user VRs (RIP, OSPF, BGP, and PIM) can be assigned to the 64 user VRs, up to a 
maximum number of 41.
