Parameters
level-1: Displays Level-1 IPv6 IS-IS SPF tree information. If you do not specify this keyword, the command displays both Level-1 and Level-2 SPF tree information.
level-2: Displays Level-2 IPv6 IS-IS SPF tree information. If you do not specify this keyword, the command displays both Level-1 and Level-2 SPF tree information.
verbose: Displays detailed IPv6 IS-IS SPF tree information. If you do not specify this keyword, the command displays brief IPv6 IS-IS SPF tree information.
process-id: Specifies an IS-IS process by its ID in the range of 1 to 65535. If you do not specify this argument, the command displays IPv6 SPF tree information about all IS-IS processes.
