                All,

                I am proposing to regularly post little scenarios to this
forum. If you see
                any benefit in this, the first is below:

                Quick Scenario 1:

                A quick scenario - should take 10 minutes to achieve.
Topology is:

                RtrA-----rtrB-------rtrC

                Rules:
                1. You can run BGP on rtrA and rtrC, but NOT rtrB.
                2. Any IGP can be run on rtrA, rtrB, rtrC.
                3. Create a loopback on rtrA and rtrC and ensure that
the opposite
                route to the loopback is visible to the remote router via
BGP.
                4. You cannot peer rtrA and rtrC with respect to BGP
                5. The origin code for your route must be the same as
the original
                origin code when the route was injected into BGP
                6. 10 minutes to complete

                I will post answers in 5 days time.

                Cheers,
