Extra info and code examples

Babel is a distance-vector routing protocol for IPv6 and IPv4 with fast convergence properties, described in RFC 6126. It was designed to be robust and efficient on both wireless mesh networks and classical wired networks. Babel has extremely modest memory and CPU requirements. Unlike most routing protocols, which route either IPv4 or IPv6 but not both at the same time, Babel is a hybrid IPv6 and IPv4 protocol: a single update packet can carry both IPv6 and IPv4 routes (this is similar to how multi-protocol BGP works). This makes Babel particularly efficient on dual (IPv6 and IPv4) networks. This implementation also includes a radio frequency-aware variant of Babel. Babel has the following features: * it is a distance-vector protocol; * it is a proactive protocol, but with adaptative (reactive) features; * it senses link quality for computing route metrics using a variant of the ETX algorithm; * it uses a feasibility condition that guarantees the absence of loops (the feasibility condition is taken from EIGRP and is somewhat less strict than the one in AODV); * it uses sequence numbers to make old routes feasible again (like DSDV and AODV, but unlike EIGRP); * it speeds up convergence by reactively requesting a new sequence number (like AODV, and to a certain extent EIGRP, but unlike DSDV); * it allows redistributed external routes to be injected into the routing domain at multiple points (like EIGRP, but unlike DSDV and AODV).
