    I have a basic doubt in Virtual Link. I am still not clear about the use or
    benifit of the VLink.

    Pl. Check RFC-2328 Fig-6. Sec-3.4. See the last line which states

    "Note that a failure of the line between Routers RT6 and RT10 will cause the
    backbone to become disconnected. Configuring a virtual link between Routers
    RT7 and RT10 will give the backbone more connectivity and more resistance to
    such failures. "

    Anyway RT7 and RT10 are connected thru network-6 and all the routers are
    having this info so that when the link fails between RT6-RT10 fails they can
    still do the routing. What is the benifit of the Vlink?

    Can u pl. give me a scenario where I will have an advantage of a VLink?
