# IP Routing Table

## Navigation

1. Right-click on the Persistent Storage Device (PSD) card and then select PSD Details.

2. In the contents pane, double-click on the Network Details folder and then select IP Routing Table.

From the IP Routing Table dialog box, you can enable/disable forwarding on this device and make changes to any route.

This dialog box displays the following data:

- Destination Address (ipRouteDest)

- Outgoing Interface (ipRouteIfIndex)

- Metric1 (ipRouteMetric)

- Next Hop (ipRouteNextHop)

- Route Type (ipRouteType)

- Routing Protocol (ipRouteProto)

- Subnet Mask (ipRouteMask)

Destination Address (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.

Outgoing Interface (ipRouteIfIndex)

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

Metric1 (ipRouteMetric)

Specifies the primary routing metric for the route.

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 object is the IP address of the agent on that interface.

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.

Routing Protocol (ipRouteProto)

Routing mechanism through which this route was learned. There are 14 possible values:

other(1) | rip(8)
local(2) | is-is(9)
netmgmt(3) | es-is(10)
icmp(4) | ciscoIgrp(11)
egp(5) | bbnSpfIgp(12)
ggp(6) | ospf(13)
hello(7) | bgp(14)

Note: Inclusion of values for gateway routing protocols is not intended to imply that hosts should support these protocols.

Subnet 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.
