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

One instance of each routing protocol is spawned for VR-Default during the XCM8800 
system boot-up, and these routing instances cannot be deleted.

User VRs are supported only on the platforms listed for this feature 

on page 798. When a modular switch contains modules 

or switches that do not support user VRs, the ports on those devices 
cannot be added to a user VR.

User VRs are the VRs created by users in addition to the system VRs. When a new user VR 
is created, by default, no ports are assigned, no VLAN interface is created, and no support for 
any routing protocols is added.

User Virtual Router Configuration Domain

When you create user VRs, you must configure each VR separately, configuring routing 
protocols and VLANs for each one. To simplify the configuration process, the XCM8800 
software supports a VR configuration domain or context. When you enter a VR command, it 
is applied to the currently selected VR context, and you can use VR commands to change 
context to a different VR. The VR commands include all the BGP, OSPF, PIM, and RIP 
commands, and the commands listed in
