NOTE: If you use the rtmp-filtering | no-rtmp-filtering parameter, 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-filtering parameter, 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.
