Which interface will it be forwarded to ?
Logical AND operation between subnet mask and IP address gives the subnet ID.
a)22.214.171.124 & 255.255.255.0 = 126.96.36.199 which is not equal to the destination so the packet will not be forwarded to the interface A.
b) 188.8.131.52 & 255.255.128.0 = 184.108.40.206 so packet can be forwarded to B.
c) 220.127.116.11 & 255.255.0.0 = 18.104.22.168 so packet can be forwarded to C.
If two IP addresses match then the packet should be forwarded to the subnet with more number of 1’s in the subnet mask.
Hence, router will forward the packet to interface B.
