As long as the destination IP address in the 192.1.144.0/20 subnet packets will be forwarded to R1 by router R2. first to calculate the range of IP addresses in the 192.1.144.0/20 subnet, the network bits of the subnet has 20 bits, the host bits have 12 bits, the host bits are all set to 1 is the broadcast address, which is also the last IP address in the subnet, the IP address is 192.1.144.0 plus the last 12 bits of I, alsoThe IP address that falls within this subnet range (192.1.144.0.192 ? 159.255) is option A and D.32.Solution.BE Question Q: Referring to the diagram, the network connected to R2 has been aggregated to 192.168.176.0/21 and sent to R1,which two packets with destination addresses will be forwarded to R2 by R1 (choose 2)? This question is the same as the previous question, based on the 21-bit mask bits can be inferred in the first 5 bits of the third 8-bit byte is the same, the difference is the next 3 bits, and 176 is written in binary form as 10110000, the network number is the smallest IP address, the broadcast address is the largest IP address, that is, 10110111, into decimal numbers is 183. then the IP subnet in the IP address range is 192.168.176.0.192.168.183.255,which can
