Route Metric

The Route Metric is used for selecting the best available path. If there are multiple routes

 

for a particular destination address, the packets are forwarded on the basis of the route

 

metric. Routes with lower metric value are given higher preference.

 

A routing protocol uses the route metric to determine which routes to include in the routing

 

table when it has two available routes to the same destination from a single routing protocol

 

(static, RIP, OSPF etc). The router includes the route with the smallest metric because it

 

considers this route to be the shortest (and therefore the best). Different routing protocols

 

calculate their metric in different ways. RIP uses hops, OSPF uses bandwidth etc. Sample

 

values: 0, 1, 10, 20… Currently all static and connected routes have a default metric of 0.

Active

When IP Forwarding is enabled for the selected subnet, a green check displays in the Active

 

column.

4.Select an entry and click the Delete button to remove the selected entry from the IP forwarding table.

5.Click the Add button to create a new static route. For more information, see Adding a New Static Route on page 4-7.

6.Click Enable (to allow) or Disable (to deny) routing between VLANs.

4.2.2.1Adding a New Static Route

Use the Add screen to add a new destination subnet, subnet mask and gateway for routing packets to a defined destination. Use the screen when an existing destination subnet does not meet the needs of the network. To add a new static route:

1.Click the Add button.

A new Configuration screen displays enabling you to add a new destination subnet, subnet mask and gateway for routing packets to a defined destination.

2.In the Destination Subnet field, enter an IP address to route packets to a specific destination address.

3.Enter a subnet mask for the destination subnet in the Subnet Mask field.

The Subnet Mask is the IP mask used to divide internet addresses into blocks known as subnets. A value of 255.255.255.0 support 256 IP addresses.

4.In the Gateway Address field, enter the IP address of the gateway used to route the packets to the specified destination subnet. Do not set the gateway address to any VLAN interface used by the switch.

5.Refer to the Status field for the current state of the requests made from applet. This field displays error messages if something goes wrong in the transaction between the applet and the switch.
