An engineer must configure local redundancy on a site. Which configuration accomplishes the task?

This configuration is incomplete and places 'tloc-extension interface' directly under 'vpn 0', which is not the correct syntax for defining the extension.

This syntax is incorrect; 'tloc-extension' is a global command or used under 'vpn 0', not directly under an 'interface' configuration in this context for redundancy.

This option includes redundant and incorrectly placed commands, such as 'interface interface-name tloc-extension interface-name', which is not valid for configuring TLOC-extension redundancy.

To configure local redundancy between two WAN Edge routers at the same site, the 'tloc-extension interface <interface-name>' command is used globally and then referenced within 'vpn 0' using 'tloc-extension <interface-name>'. This creates a logical connection between the WAN Edges, allowing them to share TLOCs and provide redundancy.
