In Cisco IOS XR Software, the BGP keychain can be configured using the global configuration mode.

A keychain is a mechanism used to store and manage keys used for secure communication. BGP keychains can be used to authenticate BGP sessions using MD5 or SHA1 authentication algorithms.

To configure the BGP keychain in Cisco IOS XR Software, follow these steps:

  1. Enter global configuration mode using the "configure" command.
  2. Create a new keychain using the "key chain" command and specify a name for the keychain.
  3. Enter key configuration mode using the "key" command and specify a key-string for the key.
  4. Specify the key-string value using the "accept-lifetime" and "send-lifetime" commands.
  5. Configure the BGP neighbor to use the keychain for authentication using the "neighbor" command and the "password" option.

So, the correct answer to the question is option C, global configuration mode.
