457 Novell uses to check serial numbers to battle copy protection
violations. You will not see this traffic if there is no servers or
workstations on your network.

Hi All,
If the labs asked RIP and SAP should not bring up the isdn
line,

I found in some books the solution,

access-list 900 deny -1 -1 0 -1 451
access-list 900 deny -1 -1 0 -1 452
access-list 900 deny -1 -1 0 -1 457

I 'm confuse for third line above, Is it needed to prevent
457 ??
I can't find explanation why 457 must be denied,

Thx,

Ali Fahmi
