I could not find anything describing an "SRR option". The closest thing was something called "SSR - Strict Source Route"[0] - is that what is meant here? If so, RFC791 then refers to the same as "SSRR", as in "strict source and record route". Does the patch below clears that up or did I confuse it with something else? Thanks, Christian.
