Also sprach Charles Sprickman >Short version is that you can export a "piece" of the registry as a >.reg file. It seems you could go to the section where MTU is set and >export it, and then simply put a link to the file on your support site. >Have the user clicky-click on the link and answer "yes" to everything, >and wham-o. Problem here being that the piece of the registry that needs to be modified will change depending on what interfaces there are on the system, how many interfaces there are on the system, maybe what phase the moon is in, and probably some other stuff. Since the entries are numbered, it could conceivably be dependant on which order the interfaces get added (ethernet card added later, or dun set up later?). >A bit off-track, but can anyone using Redback stuff give a quick yes/no >to this: >Can the Redback, on a 1483-bridged customer where the pvc is known do >dhcp based on the pvc the dhcp request comes from?

It won't send its own DHCP request, but it'll serve as a DHCP relay agent, and will add the DHCP relay agent options to the DHCPDISCOVER message...including the relay sub-option for circuit. This sub-option could be used in your DHCP server to specify what IP addresses are assigned to customers (static IP address assignment via DHCP is possible this way, or dynamically assign them, but limit each circuit to only getting x number of addresses). Incidentally, the SMS can use the DHCP info to build its secured-arp table, and with an SRAM card in it, it can preserve that secured-arp table between reboots so customers don't have to release then renew to get their connectivity back if your RedBack reboots for whatever reason. >Alex - Does VZ do one pvc/customer or group hundreds together on one >pvc still? We get one customer per pvc in Lexington (former GTE territory). -- Jeff McAdams Email: [email protected] Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456
