Customizing OSPF Services

For example, the following command sets the poll interval to 90 seconds on IP

interface 2.2.2.2:

ospf/2.2.2.2# poll-interval 90

ospf/2.2.2.2#

Using Site Manager

To specify a poll interval, complete the following tasks:

Specifying the Metric Cost

For OSPF, the best path is the one that offers the least-cost metric.

You must configure cost metrics if you want to specify a preferred path. Allow the

preferred path to retain the default cost metric value of 1, and then assign

higher-cost metric values to the less-preferred paths.

Figure 6-3

illustrates the benefit of using configurable cost metrics. Assigning the

56 Kb line a cost metric value of 10 forces OSPF to choose the faster T1 line path

as the best path, despite the extra hop, when transmitting a packet from host A to

host B.
