Hi Guys,


What would be the choice to select for following BGP question:


When performing the Cisco command "show ip bgp summary", you will be presented with a summary of each neighbor connection. What will be the entry of an established BGP connection in the state column (select one answer)?



a) Idle


b) Established


c) Active


d) Blank


Thanks!

the answer is D ..


You will not see any state entry when you do a sh ip bgp summary if the routers have formed an adjacency.

All you will be see is the number of prefixes that are learnt from that neighbor


You can see the established state by using the sh ip bgp neighbor command


eg.

MS_MIL_MET_R01#sh ip bgp summary


Neighbor V AS MsgRcvd MsgSent TblVer InQ OutQ Up/Down State/PfxRcd

172.16.2.186 4 65511 159016 159039 1605 0 0 1w0d 112

MS_MIL_MET_R01#


Here the status is established and is learning 112 prefixes from the neighbor

Thanks Narayan, I would think so as well. This is a basic one.


We are students in a cisco regional academy and this question created doubts in the minds of few students who believed this is an incorrect question and the right option is not given, which should actually be 'a number'



My interpretation is number would be seen only if state in State/pfxRcd is blank.
