BGP - How to control Ingress Traffic When using Multihoming
Network Design: We are using BGP with two ISP peers, and we are using AS Path prepending to somewhat control how traffic comes into our network.
Problem: For the most part AS path prepending is working as intended, but in some cases some networks ingress from the non-preferred ISP. There is one network in particular that we would really like to ingress through a particular ISP.
Proposed Solution: I am thinking of advertising this network to both ISPs, but with different subnet masks. Right now we are advertising the network with 24 bit mask to both ISPs. And I would like to advertise this network to the "non preferred" ISP with a 23 bit mask.

The LAN gateway performs NAT and there was a dedicate nat rule for the host i wanted to reach through VPN.
