Configuration Decisions

How you configure filters depends on the following decisions:

• Whether you want to control access to services on your network

  You should enable filtering support if you want to control access to services on your network. Filters increase security by limiting the visibility of selected services. Packet forwarding filters provide the highest level of security.

• Whether you want to reduce the bandwidth consumed by unnecessary routing traffic

  Enabling filtering reduces network traffic caused by periodic service information messages sent by routers.
