• B.R1>R3>R6
• C.R1>R4>R6
• D.R1>R2

What is an IP multicast routing protocol?

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 a MED 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?

• A.The as-path local-only includes a misconfigured regular expression.
• B.The BGP group as65010 is configured for both family inet unicast and family inet6 unicast protocol families.
• C.Your AS number of 65550 is a private AS number.
• D.The export policy as65010-out is misconfigured.
