In Linux, the standard IPv6 stack is included in the mainstream kernel distribution. However, you have to patch the kernel if you want Mobile IPv6 features. Therefore, a MIPL release is usually compatible only with a specific kernel revision (unless between Linux revisions the kernel code that has to be patched has not changed). MIPL v1.1, which is described in this section, requires Linux kernel version 2.4.26. MIPL v1.1 is based on MIPv6 specification as described in RFC 3775 [RFC3775]. The most recent MIPL release, MIPL 2.0 RC1 requires Linux kernel version 2.6.8.1. It is recommended to use MIPL 1.1, at the time of writing MIPL 2.0 RC1 is a preview release and therefore very much still work in progress.

The kernel 2.4.26 can be obtained from your favourite kernel mirror site, e.g. http://www.kernel.org

The MIPL patch mipv6-1.1-v2.4.26tar.gz can be obtained from http://www.mobile-ipv6.org
