Refer to the output of the corporate router routing table shown in the graphic.
The corporate router receives an IP packet with a source IP address of 192.168.214.20 and a
destination address of 192.168.22.3.
What will the router do with this packet?
A.
It will encapsulate the packet as Frame Relay and forward it out interface Serial 0/0.117.
B.
It will discard the packet and send an ICMP Destination Unreachable message out interface
FastEthernet 0/0.
C.
It will forward the packet out interface Serial 0/1 and send an ICMP Echo Reply message out
interface serial 0/0.102.
D.
It will change the IP packet to an ARP frame and forward it out FastEthernet 0/0.
Need Explanation on this?
it is discarding the packet because 192.168.22.0 is not on routing table? or what?
Yes discards the frame because there is no valid route for it. The 21.0/24 just gives 21.1 to 21.254, so no 22.0 network. Destination is unreachable
…and , additionally, gateway of last resort is not set
