All, Anyone know how to configure a 3Com NetBuilder to support classless routing? Here is the scenario. I have a class B that is being split up into 24s and 26s. All are being statically routed over the respective WAN interfaces to the customer prem. Most default back to our WAN interfaces (some downstream BGP peers, but not in this scenario). Customer A has a 3Com Netbuilder, with an LAN IP of x.x.200.1 /24. Customer B has a Cisco 2501 with a LAN IP of x.x.23.1 /24. This customer is configured for classless routing using the 'ip classless' IOS global command. All customers can see into this network (cust B), even within the same x.x classfull class B space. But no one in the classfull x.x can see into customer A's network. Actually, their traffic gets there, but the return traffic never leaves, because the NetBuilder is looking at the first 3 bits and ignoring it, thinking that it is local. 3Com thinks that there needs to be static routes in place. I think that this is ridiculous, and that CIDR support is necessary in today's Internet. It would entail me having to ask a customer to add over 25 static routes for networks that the default rtr (me) knows about. Does anyone know how to do this without having a CIDR-aware routing protocol like OSPF running? I have had three 3Com guys on the this ticket for over a week, with no resolution. 3Com employees can redeem their company by supplying a working solution...Anyone? Regards, -Chris
