IOS 11.0 Additional Notes - Limiting Interesting Packets
Some Macintosh applications periodically send out NBP Lookup to all zones for numerous reasons - checking same serial number for copy protection, automatic search of other servers, etc. As a result, the ISDN link will get brought up frequently and wasting usages. In 11.0(2.1) or higher, Cisco routers allow the user to configure NBP Filtering for dialer-list to prevent this problem. To do this, you should replace this line on both routers:
dialer-list 1 protocol appletalk permit |
With these lines:
dialer-list 1 list 600 access-list 600 permit nbp 1 type AFPServer access-list 600 permit nbp 2 type LaserWriter access-list 600 deny other-nbps access-list 600 permit other-access broadcast-deny |
The above example indicates you want to permit only two kinds of Type of Service for NBP Lookup to bring up the ISDN line. If you want to permit additional type, add to the example before the "deny other-nbps" statement. Make sure you need to have a different sequence number or it will overwrite the previous one. For example, if you want to also permit NBP Lookup for DeskWriter to bring up the line, the list will look like this:
dialer-list 1 list 600 access-list 600 permit nbp 1 type AFPServer access-list 600 permit nbp 2 type LaserWriter access-list 600 permit nbp 3 type DeskWriter access-list 600 deny other-nbps access-list 600 permit other-access broadcast-deny |
