Q1) Suppose a BGPv4 router receives update for prefix P which indicates AS1 is next hop (and the router has never seen P before). The router then sets its MRAI timer, but before the MRAI timer expires, the router receives another update for the same prefix with a shorter AS PATH that points to AS2 as the next hop. What should the router do?

Now, assume that before the last MRAI timer (set in the previous problem) expires the router receives another update to P with a longer AS PATH length and a next hop of AS1 again. When the MRAI timer expires, what (if anything) should the router do now?
