Two routers R1 and R2 are directly connected through an Ethernet link. Both routers are running OSPF over the Ethernet link and OSPF has been registered with BFD. R1 has been set up to transmit BFD at a 50 ms interval, but R2 can receive only at a 100 ms rate due to platform limitations. What does this mean?

1. A. After the initial timer exchang
2. B. R2 sets its transmission rate to the R1 Desired Min TX interval
3. C. After the initial timer exchang
4. D. R1 sets its transmission rate to the R2 Required Min RX interval
5. E. Timers renegotiate indefinitely, so the timer exchange phase never converges
6. F. R2 sets the P-bit on all BFD control packets until R2 sends a packet with the F-bit set

Correct Answer: B
