Refer to the exhibit. A network administrator is configuring BGP on a router. Which configuration step is needed in order to establish the BGP session with the neighbor router?
- Restart the BGP process.
- Configure the keepalive timer.
- Initialize and activate the address family.
- Advertise the networks attached to the router.
| Answers Explanation & Hints:
For a BGP session to initiate, one address family for a neighbor must be activated. On Cisco routers the IPv4 address family is activated by default; however, it may cause confusion when working with other address families. The BGP router configuration command no bgp default ip4-unicast disables the automatic activation of the IPv4 AFI. |
