Link Configuration

In the CNA configuration, a link representing an individual service provider is defined on the engine module. A link configuration block on the engine module must contain at a minimum the IP address and AS number of your service provider.

It can also contain:

• penalty and priority values that the CNA decision maker process will take into account when deciding which provider links should be used for your outbound traffic to a particular prefix.
• data required for contacting and polling the SNMP agent on your edge router

For a basic link configuration example (without polling or load optimization data), see Service Provider Access Links in Chapter 3: Configuring a New CNA Server Device of the CNA Fundamentals Guide.
