A: Router A remains the DIS and generates a new pseudonode LSP for that LAN.

B: Router A remains the DIS and NO new pseudonode LSP is generated for that LAN.

C: Router D becomes the new DIS, generates a new pseudonode LSP for that LAN, and purges the old pseudonode LSP generated by Router A.

D: 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.
