Package: quagga Version: 0.99.10-1lenny1 Tags: patch when removing an IP address from an interface with vtysh, the IP address is not removed internally in zebra. It is removed in the kernel though. This also leads to the problem that when you later try to add the IP address again, it is not added to the kernel. Presumably because zebra thinks it already is in the kernel.
This patch from Paul Evans might fix the problem: http://lists.quagga.net/pipermail/quagga-dev/2008-October/006072.html Here is a transcript that shows what happens, note that the third invocation of "sh int lo" still lists the IP address: Hello, this is Quagga (version 0.99.10).
