RIP is a widely deployed interior gateway protocol. RIP was developed in the 1970s at Xerox Labs as part of the XNS routing protocol. RIP is a distance-vector protocol and is based on the Bellman-Ford algorithms. As a distance-vector protocol, RIP router send updates to its neighbors periodically, thus allowing the convergence to a known topology. In each update, the distance to any given network will be broadcast to its neighboring router.
Supported versions of RIP are:
This command change distance value of RIP. The distance range is 1 to 255.
Routes with a distance of 255 are effectively disabled and not installed into the kernel.
outthis is the direction in which the access lists are applied.
outthis is the direction in which the prefix lists are applied.
redistribute connected. To modify connected route’s metric value, please use
redistribute connected metric.
Operational Mode Commands¶
