Router(config-if)#no routing
Passive-interface command is used in all routing protocols to disable sending updates out from a specific interface.
#passive-interface (name of the interface) It will receive updates but won't send it
route#debug ip routing
A passive interface is a feature in networking where an interface still participates in routing updates, but it does not actively send or receive information. This can be useful to prevent unnecessary routing updates from being sent out on specific interfaces, reducing network traffic and overhead.
The routers are configured with different versions of RIP. R2 is not forwarding the routing updates. The R1 configuration should include the no auto-summary command. The maximum path number has been exceeded.
to identify the directly connected networks that will be announced in RIP updates
If the routing update information contains the same major network number as configured on the receiving interface, the router applies the subnet mask that is configured on the receiving interface If the routing update information contains a different major network than the one configured on the receiving interface, the router applies the default classful mask by IP address class.
subnet mask
Dynamically, as related to a routing protocol is a type of networking technique whereby the routing protocol creates, updates and maintains the dynamic routing table.
RIPv1
