NetWare Link-Service Protocol (2)

• Supports: multicast addressing; parallel paths with load balancing; up to 127 hops (RIP only 15 hops)

• NLSP supports: hierarchical routing ( areas, domains, inter-networks <--> Level 1, Level 2, Level 3)

• Hierarchical addressing scheme:

  • area-address = network-address (32 bits) and mask (32 bits)
  • mask identifies how much of the network address refers to the area itself and how much to individual networks within the area
  • example: network address = 123456C1 mask = FFFFFF00 area = 123456; network within area = C1
