考题
Within IS－IS, the restart helper performs which task?()
A. It sends CSNPs to the restarting router.B. It periodically sends TLV 211 to the restarting router.C. It informs other routers in the domain that a router has restarted.D. It tears down adjacency and sends its entire database after 30 seconds.
考题
There are three routers on a Gigabit Ethernet LAN: Router A, Router B, and Router C. Router A is the Designated Intermediate System (DIS) at Level 1 for that LAN. Router A‘s DIS priority is 64. The LAN is a Level 1-only link. Router D has just been powered up on that same LAN and its DIS priority is 80.Which statement is true?（）A. Router A remains the DIS and generates a new pseudonode LSP for that LANB. Router A remains the DIS and NO new pseudonode LSP is generated for that LANC. Router D becomes the new DIS, generates a new pseudonode LSP for that LAN, and purges the old pseudonode LSP generated by Router AD. Router D becomes the new DIS, does NOT generate a new pseudonode LSP for that LAN, and does NOT purge the old pseudonode LSP generated by Router A
