On a second thought: I start thinking it doesn't make much sense, especially given the current context of self-tests, to explicitly test this, because it's a rather particular corner case. I think it would make more sense to introduce generic tests first. About, say, PMTU, or route exceptions, but not "tunnel causes route exception and administrative change doesn't affect PMTU". -- Stefano
