What is the default routing update period for RIPv2?
A.
15 seconds
B.
30 Seconds
C.
180 Seconds
D.
240 Seconds
Explanation:
The fact that RIP only records one route for each destination requires RIP to actively maintain the
integrity of the routing tables, which can be achieved by asking all active RIP routers to broadcast
contents of routing table to adjacent RIP routers in a fixed time interval. All received updatedinformation automatically replaces the information included in the routing table.
RIP maintains routing table depending on three timers.
Update timer.
Routing-timeout timer.
Routing-refresh timer.
Update timer can be used to update initialized routing table on a node. Each RIP node only uses
one update timer. On the contrary, both routing-timeout timer and routing-refresh timer are that
each router maintains one.
RIP router triggers update every 30 seconds. Update timer is used to record the amount of time.
Once the time is up, RIP node will produce a series of datagrams including its own routing table.
