A network administrator is tasked to set up BGP in the company's network. The administrator is defining an eBGP peering between an AOS-CX switch and a directly-connected service provider. The administrator has configured the following on the AOS-CX switch:
However, when using the "show bgp all summary" command, the state does not display "Established" for the eBGP peer. What must the administrator configure to fix this issue?
The administrator must configure 'router bgp 64500 address-family ipv4 unicast neighbor 192.168.1.1 activate' to ensure that the BGP neighbor is activated within the ipv4 unicast address family. This step is crucial for the BGP peering to be established and is often required in BGP configurations to explicitly activate the neighbor within the specific address family used for routing.

Correct Answer: C ACSP Study Guide Page 538 eBGP Peering to ISP
C. router bgp 64500 address-family ipv4 unicast neighbor 192.168.1.1 activate
From ACSP Learning book BGP : "BGP Neighbor addresses : eBGP : You must manually define each BGP neighbor on your BGP router to enable the router to establish the connection. Use this configuration: neighbor <IP-address> remote-as <AS> address-family ipv4 unicast neighbor <IP-address> activate " Correct answer is C A : There is no need multihop because directly connected service provider B : When creating process BGP on AOS-CX switch, we only need to configure AS number with command "router bgp <autonomous-system-number> D : There is no need to update source on loopback0 because the question didn't mention that service provider use this loopback to establish bgp connection.
