Host 1 and Host 2 are on Ethernet LANs in different buildings. A serial line is installed between
two Cisco routers using Cisco HDLC serial line encapsulation. Routers A and B are configured to
route IP traffic. Host 1 sends a packet to Host 2. A line hit on the serial line causes an error in the
packet. When this is detected, the retransmission is sent by:
