Fast And Hackable Redis-backed Router Advertisement Daemon

fahrrad

This is fahrrad, the Fast And Hackable Redis-backed Router Advertisement Daemon made in germany. It's still under heavy development, so don't use it in production environments!

Use cases

• IPv6 networks that require precise control over prefix assignment without using DHCPv6
• High availability routers with live configuration or frequent configuration changes

Redis database

The database has to provide the following keys:

• fahrrad/mac/{BINARY_MAC} → {BINARY_PREFIX}: {BINARY_MAC} is the link-layer address of a client in binary form (i.e. aa:bb:cc:dd:ee:ff → \xaa\xbb\xcc\xdd\xee\xff) and {BINARY_PREFIX} the IPv6 prefix (/64) that this client should get advertised (i.e. 2001:db8::/64 → \x20\x01\x0d\xb8\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00)

Build and run

You need redis installed and running on tcp port 6379. Furthermore, your golang environment should be configured correctly with $GOPATH/bin in your $PATH variable.
