Refer to the exhibit. A network administrator is configuring BGP on router RT2, but RT2 cannot establish a peer relationship with RT1. What is the cause of the problem?

• An IPv4 multicast address should be used in the neighbor statement.
• The network statement for the network 192.168.2.2/32 is missing.
• The network statement for the network 17.0.0.0/16 is missing.
• The IPv4 address family has not been activated.

Explanation: In order to establish BGP neighbor and allow BGP communications, the address family needs to be activated. Cisco IOS activates the IPv4 address family by default. The BGP router configuration command no bgp default ip4-unicast disables the automatic activation of the IPv4 AFI. Thus it is necessary to initialize the address family with the BGP router configuration command address-family afi safi before activating the address family for the BGP neighbor with the the command neighbor ip-address activate .
