# IP Route

Device > Configure > IP Route

From the IP Route dialog box, you can enable/disable forwarding on this device, as well as make changes to any route.

This dialog box displays the following data:

- Destination (ipRouteDest)
- Next Hop (ipRouteNextHop)
- Mask (ipRouteMask)
- Routing Protocol (ipRouteProto)
- Port (ipRouteIfIndex)
- Hop Count (ipRouteMetric1)
- Route Type (ipRouteType)
- Route Age (ipRouteAge)

The following list specifies buttons in this dialog box, as well as their function:

- Click OK to continue.
- Click Apply to save the changes in the dialog box.
- Click Cancel to close the dialog box.
- Click Delete to delete an existing IP route.
- Click Refresh to update the contents of the dialog box.
- Click Print to print the contents of the dialog box.
- Click Help to access online help.

Destination (ipRouteDest)

Destination IP address of this route. An entry with the value "0.0.0.0" is considered a default route.

Note: Multiple routes to a single destination can appear in the table. Access to multiple entries depends on the table access mechanisms defined by the network management protocol in use.

Next Hop (ipRouteNextHop)

IP address of the next hop on this route. In the case of a route bound to an interface which is realized through broadcast media, the value of this field is the IP address of the agent on that interface.

Mask (ipRouteMask)

Indicates the mask to be logical-ANDed with the destination address before being compared to the value in the ipRouteDest field. For systems that do not support arbitrary subnet masks, the agent constructs ipRouteMask by determining whether the corresponding ipRouteDest object belongs to a class A, B, or C network.

Class A | 255.0.0.0
Class B | 255.255.0.0
Class C | 255.255.255.0

Note: If the value ipRouteDest is "0.0.0.0" (the default value), then the value of the mask is also "0.0.0.0". All IP routing subsystems implicitly use this convention.

Routing Protocol (ipRouteProto)

Routing mechanism through which this route was learned. Inclusion of values for gateway routing protocols is not intended to imply that hosts should support these protocols.

Port (ipRouteIfIndex)

Index value which uniquely identifies the local interface through which the next hop of this route should be reached.

Hop Count (ipRouteMetric1)

Specifies the primary routing metric for the route.

Route Type (ipRouteType)

Specifies the type of route. There are 4 possible values:

other (1) | none of the following
invalid (2) | an invalid route
direct (3) | route to directly connected network or subnetwork
indirect (4) | route to a non-local host/network/subnetwork

Note: Whether the agent removes an invalid entry from the table is implementation–specific.

Route Age (ipRouteAge)

Number of seconds since this route was last updated or otherwise determined to be correct.
