Anycast Helper

Small helper adding and removing Anycast IPs from interfaces depending on listeners

Usage

anycast-helper --anycast-ip 192.168.32.1 --port 1234

• Requires at least CAP_NET_ADMIN beacause it needs write access to netlink
• Uses (and creates) the anycast0 interface for binding IPs to, this interface should be monitored by the routing daemon
• Sync period is fixed to 500ms which should be plenty fast while using extremely little resources
