JN0-281 · Question #10
Which two statements are correct about rules for EBGP and IBGP? (Choose two.)
The correct answer is A. EBGP peers have a TTL of 1, while IBGP peers have a TTL of 255. C. EBGP routes are more preferred than IBGP routes. EBGP (External BGP) and IBGP (Internal BGP) operate with different rules due to the nature of their relationships. TTL Differences: EBGP: By default, EBGP peers have a TTL of 1, meaning they must be directly connected, or the TTL needs to be manually increased for multihop…

Explanation
EBGP (External BGP) and IBGP (Internal BGP) operate with different rules due to the nature of their relationships. TTL Differences: EBGP: By default, EBGP peers have a TTL of 1, meaning they must be directly connected, or the TTL needs to be manually increased for multihop EBGP. IBGP: IBGP peers within the same AS have a TTL of 255, as they are expected to communicate over multiple hops within the AS. Preference for EBGP Routes: Routes learned via EBGP are typically preferred over IBGP routes. This is because EBGP routes are considered more reliable since they originate outside the AS, while IBGP routes are internal.
