Which two statements describe the usage of the IS-IS overload bit technique? (Choose two )

• A.lf overload-bit is set on a Level 2 intermediate system, the other Level 2 intermediate systems in the topology will stop using the overloaded IS to forward Level 2 traffic However, the intermediate system can still forward Level 1 traffic
• B.It can be used to automatically synchronize the link-state database between Level 1 intermediate systems
• C.It can be set in intermediate systems (IS-IS routers) to attract transit traffic from other intermediate systems
• D.It can be set in intermediate systems (IS-IS routers) to avoid traffic black holes until routing protocols are fully converged after a reload operation.
• E.It can be set in intermediate systems (IS-IS routers) to prioritize control plane CSNP packets.

Two routers (R1 and R2) run OSPF and have registered with BFD in asynchronous mode with the echo function enabled. Which two actions occur with the echo function? (Choose two)

• A.BFD control packets are sent at a slower pace because the echo function is enabled
• B.BFD echo packets are sent from forwarding engines along the Layer 2 path to perform detection
• C.BFD control packets are sent at a higher pace because the echo function is enabled
• D.Only BFD control packets are sent from forwarding engines along the Layer 2 path to perform detection
• E.BFD sessions at either end actively participate in the forwarding of echo packets
