BGP Community

The bgp-community command allows you to associate a BGP community string with a prefix, or group of prefixes. This is especially useful when optimizing a VPN, for example, as described in Chapter 3: VPN Integration of the CNA Advanced Monitoring Guide.

The CNA system automatically associates the string no-export with all routes that it asserts.

If you specify a community string with bgp-community all command, your new string will overwrite the default no-export string. If you want this behavior to remain in effect, you must include no-export in your list of arguments.
