Lets say I have the following network of 4 machines A,B,C,D A1--------B1 (speaking OSPF) On 10.0.0.0/28 And I have C1--------D1 On 11.0.0.0/28 I want to setup it up so that all 4 now have a common physical interface on the new hub. I will then setup the 4 interfaces to be on the 12.0.0.0/8 network A1---------B1 | | +++++Hub++++ | | C1---------D1 So I ifconfig A2 (i.e. the second interface on A) to 12.0.0.1/8, no problem. The route, 12.0.0.0/8 gets installed into the local routing table, and gets redistributed via OSPF to the machine B1. Now, on B I do ifconfig B2 12.0.0.2 netmask 255.0.0.0 I get the error ifconfig: ioctl (SIOCAIFADDR): File exists Because the route is already installed locally as pointing to machine A via interface B1. (.i.e. I have redistribute connected enabled) Short of killing ospfd and zebra how do I get around this ? I tried the same in zebra (ip address 12.0.0.2/8, but I get the error, "File Exists" which means that the route exists I guess. ---Mike -------------------------------------------------------------------- Mike Tancsa, tel +1 519 651 3400 Sentex Communications, mike@sentex.net Providing Internet since 1994 www.sentex.net Cambridge, Ontario Canada www.sentex.net/mike
