The exhibit shows the complete BGP configuration for a router. The network operator reports that both peering sessions are up, but the router is not conducting per-flow load balancing over the connections to these two peers.
What are two causes for this behavior? (Choose two.)
A. The router has different IGP metrics to these BGP peers.
B. The multiple-as parameter causes BGP to only choose multiple paths to different ASs, rather than multiple paths to the same AS.
C. The BGP peers are not sending identical advertisements over the two sessions.
D. The forwarding-table export policy is not configured to cause per-flow load balancing.
正解：C,D
