A BGP network has been designed to provide resiliency and redundancy to a multihomed customer network. Which two statements are correct in this scenario? (Choose two.)

The correct answer is B. A routing policy will be required to forward traffic to both next hops. C. The TTL value of 1 is set to limit the scope of the EBGP session. B - Because only one next hop in forwarding table. C- Becuse TTL=1 limiting bgp connection to be established only over loopbacks interface. Use the multihop statement to alter the default use of the neighbor's physical address. In addition, you can also specify a time-to-live…

Explanation

B - Because only one next hop in forwarding table. C- Becuse TTL=1 limiting bgp connection to be established only over loopbacks interface. Use the multihop statement to alter the default use of the neighbor's physical address. In addition, you can also specify a time-to-live (TTL) value in the BGP packets to control how far they propagate. We use a TTL value of 1 to ensure that the session cannot be established across any other backdoor links in the network.
