Say what? Why don't you just create additional VLANs for the new address space(s) and move PC's to the new VLANs as their addresses are changed? There is no need to be messing around with dual default routes. You could move all of the switches over to the new address space immediately, or change them over time to the new address and VLAN.
If you are not using VLANs, then why did you purchase 4506s, 3550s, and 6509s?

Our network is all statically mapped no dynamic routing our switches(4506,3550,6509) are going to be changed to a different address range. the switches can accept more than one default gateway. The core routers addresses has to be changed to the same subnet as the switches soon 1)the switch old ip address is on a 11/8 address pointing to the core router(interface) with a 11/8 address 2)now the switch addresses are being changed to a 10/16(subnetted) address and the default gateway has to point to the core with a 10/16 address as well Myu approach was to 1)configure the swith with another default pointing to a 10/16 2)configure a secondary interface on the core with a 10/16 address 3)the other core routers connected to this core will be also given a secondary of 10/16 address 4)then on the core routers put floating statics for all our original routes to point to the default GW 10/16 addresses I presume that because the swithes now have to defalt GW statements that the swith will automatically send packest for pc's of 10 and 11 addresses. While we slowly migrate all our lan devices to the new 10/16 GW 5)will start gradually changing the lan devices to start pointing to the 10/16 GW Please correct me if im thinking of this the wrong way. Any advice will be greatly appreciated My apologies if I didnt explain myself properly regards, seun Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=72301&t=72288 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
