   A network engineer is configuring IS-IS on a router and wants to ensure that the router advertises its loopback address in the LSP. The loopback address is 10.1.1.1/32. Which TLV will carry this information?

   • ATLV 1 (Area Addresses)
   • BTLV 22 (Extended IS Reachability)
   • CTLV 132 (IP Interface Address)
   • DTLV 135 (Extended IP Reachability)

   An engineer is reviewing the LSP of a Level 2 router and sees a TLV 22 (Extended IS Reachability) with a neighbor ID of 1920.0000.0000.0001 and a metric of 100. What does this TLV indicate?

   • AThe router is indicating that the neighbor is a Level 1 router with a metric of 100.
   • BThe router is advertising a default route through the neighbor with a cost of 100.
   • CThe router is advertising a route to the neighbor's loopback address with a cost of 100.
   • DThe router has a direct adjacency with the neighbor and the cost to reach it is 100.

   A router receives an LSP with a TLV that has a Length field of 255. The PDU is only 200 bytes long. What will the router do when parsing this TLV?

   • AIt will ignore the TLV and continue with the next one.
   • BIt will truncate the TLV to fit within the PDU and continue parsing.
   • CIt will read 255 bytes of value data, even if it extends beyond the PDU.
   • DIt will discard the entire LSP as malformed.
