Chapter 5: FN10 Filters
This filter is configured as follows:
• Filter identifier – port number of the port attached to LAN 2 as a
destination (i.e., exit)
• Filter identifier – port number of the port attached to LAN 3 as a
destination (i.e., exit)
• Filter fields – protocol type = AppleTalk I, match source LAN = LAN
1, match destination address, match
This filter blocks AppleTalk I multicasts (or all AppleTalk I traffic if the
destination address field is omitted) from LAN 1 to LANs 2 and 3, yet
AppleTalk I traffic to LAN 4 is permitted because LAN 4 is not specified
for filtering.
