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.
