Classify each of the following as a property of static or dynamic routing protocols: (out of 7): [1 point each] No. Property Routing protocol 1 Use more memory 2 Use more CPU time 3 Used in stub and edge routers 4 Use more amount of bandwidth s Routers change very slowly over time 6 Save large amount of time and energy on configuring the routers 7 Susceptible to routing loops and oscillation in routes
