0/26, it will send it to the Router C. 0/26 is directed towards Router B and will send it back. This loop shall continue until the IP TTL value in the packet reaches zero and a router drops it. In order to avoid routing loops, Distance Vector Protocols have established some restraints, as discussed below.
