How would you complete the following BGP configuration to allow the BGP router in AS 65111 to only accept BGP updates from AS 65101 having 172.16 in the first 16 bits and a subnet mask of 24 bits or less? (Any other updates from AS 65101 are denied.)

Explanation:
neighbor 10.1.1.1 prefix-list test in
ip prefix-list test seq 5 permit 172.16.0.0/16 le 24Answer should be
ip prefix-list test 5 permit 172.16.0.0/16 let 24. 172.16.0.0 /16 is the correct network length statement,
while le 24 is the mask to permit
