What two conclusions can you draw from this BGP summary? (Choose two.)

Show Answer
Correct Answer: AB

The BGP session with the peer 10.127.0.75 is established, as indicated by the uptime and the received prefixes. External BGP (EBGP) exchanges routing information because the AS numbers of the neighbors are different from the local AS number, signifying EBGP sessions.

Page 210 in the Study Guide gives a good overview of the command get router info bgp summary and it's output. C - You can't see if BFD is enabled with get router info bgp summary. For that you would run get router info bfd neighbor. So C doesn't quite make sense as a correct answer, as the information to answer that is lacking. D: Is just plain wrong, the "4" they are reffering to, and which you see in the output refers to IPv4 which is being used in the BGP configuration. Thus A & B is correct. A because the peer state is indeeed established, showing up-time and that is has received 1 prefix. B because the peers are indeed eBGP peers and are exchanging routing-information.

... or they took the documentary AS number space to simulate ebgp. Somehow confusing. If this is the case, I would take A and B

It does not matter if the ASNs are private or public. What matters is that the neighbors' ASNs are different than the local ASN which makes it EBGP

Think I have to revert. B states that "external" bgp exchanges routes. Oversaw that we have here no public AS range. 0-64.495 would bei public 65.512-65.534 is private
