Is it possible to advertise single IP or /27 subnet in internet. As I know, only /24 pool or less (/23, /22, 21 etc.. ) should be advertise into internet.
Scenario : I have two internet link from two ISP and planning to buy /24 pool from APNIC. I wanted to choose one /27 pool subnet to be reacble via Link B. and rest all IPs via Link A. Also if any one link fails than it should be reachble via other link and vice-versa.
I have IP pool as 22.214.171.124/24.
Two Links : Link-A & Link-B
126.96.36.199/27 should use LINK-B as primary path
Rest all IP subnets ( 188.8.131.52/27, 184.108.40.206/26, 220.127.116.11/25 ) should use Link-A as primary path.
If any link fails, all subnet should be reacble via next link.
