I have done this when a contractor had set up our border router with the wrong subnet mask you can change with zero down time as long as all hosts are configured correctly

We are changing our subnet mask to add a new network. Its is on a 4700 router with ip classless setup. We use real IP's but i'll but private ones on the example.. Ex. eth0 is now 172.16.10.0/24. I want to split this network in half so I wish to make eth0 172.16.10.0/25 and eth1 172.16.10.128/25. Eth0 leads to our production network. I want to have this change over with zero downtime. The Ip address on the interface (172.16.10.1) must stay the same. Is there anyway to change the subnet mask only with zero downtime? UNIX allows you to put 2 statements on a singel line split by a ; . Does cisco ios have something simliar? sam sneed Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=21606&t=21576 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
