Router(config-if)#no routing
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
The question is incomplete. No options (for which of the following) are given to answer the question.
Two Characteristics: RIP is an example of distance vector routing protocols. Updates are periodic and include the entire routing table
Distance vector routing protocols send routing table updates primarily under three conditions: when a router's routing table changes due to a new route being added or an existing route being updated, when a router receives a triggered update from a neighboring router indicating that a route has changed, and periodically at defined intervals to ensure all routers have consistent routing information. These updates help maintain accurate and up-to-date routing tables across the network.
RIP routing updates are sent every 30 seconds by default. In RIP version 1, they are sent as a broadcast. In RIP version 2, they are sent to a special multicast address.
RIP VERSIONV1 can be seen to exclude subnet information from routing updates, this is because ripv1 is a classful routing protocol and does not support VSLM, this was corrected in RIPv2 where ripv2 does send out subnet mask's in the form of a prefix eg /24 which is the subnet mask of 255.255.255.0 or a class c address.
RIPv2 sends subnetmasks in the routing table updates. RIPv1 does not, which causes it be class-full.
It excludes subnet information from the routing updates
