- DoD Internet RIP
-
- This packet is carrying routing
-
- information between routers on an IP-
-
- based internet. It contains information
-
- about various networks and a metric for
-
- the distance to each; in most cases,
-
- this metric is a simple hop count. Note
-
- that a distance metric of 16 indicates
-
- that the network in question is
-
- unreachable via the router transmitting
-
- the packet. Routing Information Protocol
-
- (RIP) packets are transmitted by each
-
- router approximately once every 30
-
- seconds, and are useful in determining
-
- the connectivity of an IP network.
-
- Internet RIP was designed as an interior
-
- gateway protocol (IGP), that is, for use
-
- with moderate-size networks using
-
- reasonably homogeneous technology.
