    Vijay,

    Since virtual links belong to the backbone, with such a link there will
    always be a path between any two backbone interfaces via backbone links
    only. Thus, even without RT6 - RT10 line, RT10 is no longer isolated,
    provided the other routers are intact, and the virtual link is up.
