You are configuring an EBGP peer in a transit environment. You must advertise routes learned from other EBGP peers in your AS. Any routes originated from within your AS should have a MED of 7000 set. Any routes that originate in AS65222 should be prepended four times. Any routes that transit AS701 should have aMED set to 6. This scenario results in the unintended advertisement of internal 10.0.0.0/8 networks to your peer. What caused the accidental advertisement of internal networks to your EBGP peer?

1. A. Your AS number of 65550 is a private AS number.
2. B. The BGP group as65010 is configured for both family inet unicast and family inet6 unicast protocol families.
3. C. The export policy as65010-out is misconfigured. — đáp án hiện tại
4. D. The as-path local-only includes a misconfigured regular expression.
