Which command can be used with the Cisco IOS VRF migration tool to ensure that all route-target policies are copied to their respective address families?
- vrf upgrade-cli multi-af-mode common-policies
- vrf upgrade-cli multi-af-mode non-common-policies
- vrf upgrade-cli multi-af-mode vrf
- vrf upgrade-cli multi-af-mode policy vrf
Explanation: When migrating from the legacy single-protocol VRF configuration (ip vrf) to the modern multiprotocol VRF configuration (vrf definition), the Cisco IOS migration tool provides options for how existing route-target policies are handled:
- common-policies: Copies the route-target policies to the global/common part of the new VRF configuration. This ensures that the import and export policies apply automatically across all configured address families (such as IPv4 and IPv6) within that VRF.
- non-common-policies: Keeps the route-target policies restricted to the IPv4 address family sub-mode only, preventing them from automatically applying to other address families.
