1. Enter the required information:

Virtual Router Name: Indicates the name of the VR.

Virtual Router ID: Indicates one of two settings that identify the VR.

Use System Default: Indicates that the IP address of the VR acts as the ID of the routing instance.

Custom: Enables you to set an IP address to identify the virtual routing instance that is different from the default address.

Management VR: Designates this VR as the management virtual router (MGT VR). A MGT VR supports the out-of-band management infrastructure and segments security device management traffic away from production traffic.

Maximum Route Entry: Indicates the upper limit of the number of routes the VR can store in its routing table.

Unlimited: Indicates that the current virtual routing instance has no upper limit for the number of routes it can store in its routing table.

Set Limit At: Enables you to set a specified upper limit for the number of routes the current VR can store in its routing table.

Maximum ECMP Routes: Enables you to set a specified upper limit for the maximum number of equal cost multipath (ECMP) routes that can exist for each protocol and for static routes in a routing table. Specify 2, 3, or 4. Setting the limit enables ECMP routing so that the security device can perform load balancing between ECMP routes.

Route Lookup Preference: Specifies the order in which the VR performs route lookup, if source-based routing or source interface-based routing (SIBR) is enabled in the VR. The VR checks the routing table with the highest preference value first.

For Destination Routing: Assigns a preference value for the destination-based routing table. The default value is 1. Enter a value between 1 and 255.

For Source Based Routing: Assigns a preference value for the source-based routing table. The default value is 2. Enter a value between 1 and 255.

For Source Interface Based Routing: Assigns a preference value for the SIBR routing table. The default value is 3. Enter a value between 1 and 255.

Use default route: (For the trust-VR only) Adds a default route with the specified VR as the next hop.

Shared and accessible by other vsys: Indicates that the root-level local VR is accessible from a virtual system (vsys). The untrust-VR is, by default, shared by all other vsys.

Ignore Subnet Conflict for Interfaces in This VRouter: Directs the VR to ignore overlapping subnet addresses for interfaces in the VR.

Make This VRouterDefault-Vrouter for the System: Sets this VR as the default VR for the vsys. The trust-VR is the default VR for the root system.

Auto Export Route to Untrust-VR: Directs the VR to export public interface routes to the untrust-VR.

Make SNMP Trap Private: (This option is only available for the default root-level VR.) Enables you to make Simple Network Management Protocol (SNMP) traps for the dynamic routing MIBs private for the VR.

Enable Source Based Routing: Enables source based routing on this VR.

Enable Source Interface Based Routing: Enables source interface-based routing on this VR.

Advertise Routes on Inactive Interfaces: Directs the VR to consider active routes on inactive interfaces for advertising.

Permit sync VR configure to NSRP peer: Directs the VR to synchronize its configuration with the VR on its NetScreen Redundancy Protocol (NSRP) peer.

Route Preference: Displays various ways to identify the desirability of a route in the current VR. The lower the value, the more probable the VR will select the route.

Auto Exported: Indicates the level of desirability associated with the decision the current VR makes to select an automatically exported route from other VRs on the network.  

Imported: Indicates the level of desirability associated with the decision the current virtual routing instance makes to select a route imported from another VR on the network.  

EBGP: Indicates the level of desirability associated with the decision the current VR makes to select a route originating from an Exterior Border Gateway Protocol (EBGP) router.

OSPF: Indicates the level of desirability associated with the decision the current VR makes to select a route originating from an Open Shortest Path First (OSPF) router.

RIP/RIPng: Indicates the level of desirability associated with the decision the current VR makes to select a route originating from a Routing Information Protocol (RIP) or a Routing Information Protocol Next Generation (RIPng) router. RIPng is intended only for use in IPv6 networks.

Connected: Indicates the level of desirability associated with the decision the current VR makes to select a route sent from a router that has at least one interface with an IP address assigned to it.

Static: Indicates the level of desirability associated with the decision the current VR makes to select a static or manually configured route.

IBGP: Indicates the level of desirability associated with the decision the current VR makes to select a route originating from an Interior Border Gateway Protocol (IBGP) router.

OSPF External Type 2: Indicates the level of desirability associated with the decision the current VR makes to select OSPF External-Type-2 routes.

2. Click OK to save your changes and return to the Virtual Router List. Click Apply to continue configuring the VR.

If you clicked Apply, the Dynamic Routing Protocols Support area displays with the following links:

BGP: A link for creating a Border Gateway Protocol (BGP) routing instance. For more information, see Virtual Router BGP Settings.

OSPF: A link for creating an OSPF routing instance. For more information, see OSPF Virtual Router Settings.

RIP: A link for creating a RIP routing instance. For more information, see RIP Virtual Router Settings.

RIPng: A link for creating a RIPng routing instance. For more information, see RIPng Virtual Router Settings.

Next Hop Resolution Protocol (NHRP) Support: If you are configuringAC-VPN,click NHRP Setting to enable NHRP and configure Next Hop Client (NHC) cache entries.
