Junos "show bgp summary" shows different outputs for neighbors
The "show bgp summary" in Junos shows all configured or established neighbors (there can be RR clients that are not configured, but are established).
More information about output of "show bgp summary" is documented on Juniper website:
http://www.juniper.net/documentation/en_US/junos15.1/topics/reference/command-summary/show-bgp-summary.htmlThe output includes both internal and external neighbors with a small difference. Internal neighbors (even they only use ipv4 unicast AFI/SAFI) show up as "ESTABL" and a line below shows the RIB and statistics.
For external BGP neighbors, the statistics are shown on the same line as the neighbor.
Code:
[edit protocols bgp]
admin@PPPPP# run show bgp summary

inet6.0: 1/1/1/0
10.0.255.3 is eBGP
10.0.255.7 is iBGP.
This is most probably because L3VPN and L2VPN routes (bgp.l3vpn.0 RIB) are exchanged over internal BGP sessions and this output is optimized to better account for this fact.
