hello. I'm not sure if this is the right mailing list to ask, but I hope that someone could possiably help.. I have a network with a cisco 2501 router running IOS 10.2(9), and we have a block of addresses from our internet service provider (60 addresses, 206.206.162.128, start. with 1 for network, and 1 for brodcast) we recently requested another block of 32 from our ISP, and they gave us the following: 207.66.81.96, start...with 1 for network/1 for brodcast. I asked a similar question on a mailing list before (not sure if it was this one) and was told to login to the router, then: router> en pass:..... router# conf term router <conf> int e 0 router <subif> ip address existing_ip existing_subnetmask secondary crtl-z write i tryed this, but it did not work. I also tryed replacing the exiting ip/subnet with the new one... but that did not work either... am i doing something wrong? or do i just need a 11.xx(xx) IOS ? Any help would be greatly apreciated. thanks. =-=-=-=-=-= -Kyle Donald Smith -Systems Administrator -Community Internet Access, Inc. -peaches@cia-g.com
