# Virtual Router List

The ScreenOS divides its routing component into two predefined virtual routers—Untrust-VR and Trust-VR. By default, all zones are bound to the Trust-VR. You can assign zones to the Untrust-VR virtual router.

The virtual router table displays information in the following columns:

VR ID: The ID number of the virtual router. The ID numbers of the default virtual routers are 1 for Untrust-VR, and 2 for Trust-VR.

Name: Lists the two default virtual routers: untrust-vr and trust-vr.

Access List: Indicates how many access lists have been configured for the virtual router. To view the access lists, click Access List. For more information, see Virtual Router Access List.

Route Map: Indicates how many route maps have been configured for the virtual router. To view the route map list, click Route Map. For more information, see Route Map List.

Import Rules: The number of route import rules that you have created for the virtual router. (You can import specific routes from one virtual router to another. Note that to remove a route from the destination virtual router, you must either delete the route from the source virtual router or change the route import rule.) To view the import rules list, click Import Rules. For more information, see Import Rules List.

Export Rules: The number of route export rules that you have created for the virtual router. (You can export specific routes from one virtual router to another.) To view the export rules list, click Export Rules. For more information, see Export Rules List.

DRP: Indicates the dynamic routing protocol configured for the virtual router.

O: Indicates the virtual router was configured with the Open Shortest Path First (OSPF) protocol.

B: Indicates the virtual router was configured with the Border Gateway Protocol (BGP).

R: Indicates the virtual router was configured with the Routing Information Protocol (RIP).

If the code appears in green, the protocol has been enabled for the virtual router. If the code appears in red, the protocol has been disabled for the virtual router or has not yet been enabled. All protocols are disabled by default. You must enable a protocol after first configuring it for the virtual routing instance.

Route Entries: The number of route table entries in the virtual router. To view the routing table, click Route Entries. For more information, see Route Table List.

Configure: Click Edit to modify a virtual router. Click Remove to remove a user-defined virtual router. (You can only remove a user-defined virtual router if there are no zones in that virtual router. You cannot remove the Untrust-VR or the Trust-VR.)

In addition, to select how many virtual routers per page you want to view, select 5, 10, 20, 50 or 100 in the List per page drop-down list.

### To Add a New Virtual Router
