On an OSPF network, if two routers with the same router ID run in different areas and one of the routers is an ASBR, LSA flapping occurs.

See the network shown in the following figure.   R1 and R2 run IS-IS and establish an adjacency. IS-IS is enabled on Loopback0 of R2 but disabled on Loopback3 of R2. The configurations shown in the figure are performed in the IS-IS process of R2. Which of the following statements are true?

BGP is generally applied to complex networks where routes change frequently. Frequent route flapping consumes a large number of bandwidth and CPU resources, and even affects the normal operation of the network. This is an unavoidable problem that cannot be solved in BGP.

On an OSPF network, if a router functions as an ABR, the router must also be a BR. 

On an OSPF network, if a router functions as an ABR, the router must also be a BR.
