• Question 171:

  IS-IS LSP fragments are identified by the LSP Number field in their LSP IDs. This field is 4 bits long. Therefore, an IS-IS process can generate a maximum of 256 LSP fragments , which means only a limited amount of information can be carried. By adding additional system IDs, you can enable the IS-IS process to generate more LSP fragments.

  Options:

  A. TRUE
  B. FALSE
  A. TRUE
