Hi everybody.
Let say we have two routers, r1 and r2 , both understand " good bye" message if for any reason they have to drop adjacency they can send " good bye" message and drop the adjacency.
Now what if we have two routers say r3 and r4. r3 is a new router and therefore understands " good bye " message, while r4 does not.
r3--------------r4.
Let say both routers above have formed adjacency. Suppose for some reason, r3 has to drop the adjacency, r3 therefore crafts a " good bye" message (i.e all k,svalues set to 255). How will r4 react upon receiving this goodbye message? Will r4 drop the adjacency? or will r4 continue to wait until hold timer expires and then drop the adjacency?
thanks and have a great day.
