15. Select the Save link at the bottom of the dialog. Select Yes when prompted to save the configuration change
to the startup-config file on the device's flash memory.
Network Filtering
EXAMPLE:
To deny access to the Finance server to users within the Marketing and Field Service zones on the network and to
prevent information about the zone and the network numbers from being forwarded out of interface 1 (Figure
24.2), use one of the following methods.
USING THE CLI
BigIron(config-if-1)# appletalk deny zone finance rtmp-filtering
USING THE WEB MANAGEMENT INTERFACE
To enable RTMP filtering on an interface, define the filter as usual, then enable the RTMP filtering option on the
AppleTalk Zone Filter panel.
Routing Between AppleTalk VLANs Using Virtual Interfaces
In addition to supporting AppleTalk VLANs, Foundry routers support routing between AppleTalk VLANs using
virtual interfaces. The virtual interfaces provide VLANs access to the router functions of Foundry routers. Using
these virtual interfaces eliminates the need to assign a physical port for routing between local VLANs.
AppleTalk routing between virtual and physical interfaces is also supported.
EXAMPLE:
In Figure 24.3, AppleTalk traffic is terminating on ports 1 through 4. Suppose you want to group all of these
interfaces into an AppleTalk protocol VLAN and route traffic to VLANs on other routers.
To do so, perform the following steps:
1. Create an AppleTalk protocol VLAN with port membership of ports 1, 2, 3, and 4.
2. Assign a virtual interface to the AppleTalk VLAN to allow it to route traffic to AppleTalk VLANs on remote
routers.
3. Configure a physical interface on the router that provides access to remote networks to support routing
between local and remote AppleTalk VLANs.
NOTE: By supporting assignment of VLANs on interfaces, the router is functioning as a virtual Layer 2
Switch.
