Advanced Configuration and Management Guide

NOTE: If you use the rtmp-filtering no-rtmp-filteringparameter, you are configuring an AppleTalk network filter. See the following section.

Appletalk Network Filters

Routing Table Maintenance Protocol (RTMP) filtering enhances a zone filter by hiding the cable ranges inside the zones used by other routing switches. The denied network numbers of the filtered zone will be removed from the RTMP packets.

The Macintosh chooser uses ZIP GetZoneList request to compile a list of zones available, so if the zone is not there the Macintosh computer cannot access it. RTMP filtering is useful for preventing downstream and adjacent routers from responding to GetZoneList requests that could give access to the zones you want to filter. All routing switches on the same segment should be configured with the same filters. You can prevent local Macintosh computers from accessing a zone but still allow the downstream routers with Macintosh computers attached to other networks to access those zones. To do so, do not use the RTMP filtering option with the zone filter.

When you configure an AppleTalk zone filter to also filter network information, the device removes route information for the networks in the specified zone before sending the RTMP packet out on the port.

Actions

AppleTalk network filters remove information about the networks in the denied zones before sending RTMP packets to Macintosh computers.

NOTE: AppleTalk network filters only deny information; they do not permit information.

Scope

You configure and apply AppleTalk network filters on individual ports.

Syntax

Use the following CLI commands or Web management interface panels to configure AppleTalk zone filters.

NOTE: If you do not use the rtmp-filtering no-rtmp-filteringparameter, you are configuring an AppleTalk zone filter.

BGP4 Filters

Border Gateway Protocol version 4 (BGP4) filters control the routes that a device learns from BGP4 neighbors and advertises to BGP4 neighbors. You can configure filters to filter route information based on network address, AS-path, or community name.

BGP4 Address Filters

BGP4 address filters control whether the device learns or drops BGP4 route information based on the route’s network address.
