In a nutshell, the RIP principle is that routers Exchange routing table information to form neighbor relationships
RIP metric (hop count)
The maximum number of hops specified in RIP is 15.16 hops as the administrative distance of the unreachable RIP protocol is 120 by default
Update time for RIP
RIP uses UDP protocol, port number is 520
After the router starts, an average of 30 seconds will be sent from each interface that initiates the RIP protocol to continuously send a way out by updating the message
(a) There are two versions of the RIP protocol, RIPV1 and RIPv2, the main differences are as follows:
RIPV1 broadcast sends routing updates, broadcast addresses send routing updates for 255.255.255.255,ripv2 group advertisements, multicast address is 224.0.0.9
RIPV1 is an inter-class routing protocol that does not carry a subnet mask when declaring information
RIPv2 is a class-free routing protocol that carries a subnet mask when declaring information
(ii) Another feature of the Inter-Class routing protocol is the automatic summarization on boundary routing
Experimental requirements:
Full Network interoperability
Configure the router's interface address
Initiates the RIP process on the router and declares the main network number
RIP is a distance vector routing protocol
The following configuration is RIPV1
The topology diagram is as follows:

With RIPV1 on the router, the steps are as follows
