Implementing and Operating Cisco Service Provider Network Core Technologies (SPCOR) — Question 238

An engineer is moving all of an organization's Cisco IOS XE BGP routers to the address-family identifier format. Which command should be used to perform this upgrade quickly with the minimum service disruption?

Answer options

• A. vrf upgrade-cli
• B. bgp upgrade-cli
• C. address-family ipv4
• D. ip bgp-community new-format

Correct answer: B

Explanation

The correct command is 'bgp upgrade-cli' because it is specifically designed for upgrading BGP configurations. The other options either pertain to VRF configurations, configuring address families without an upgrade context, or changing community formats, which do not facilitate the intended upgrade process.
