DECnet Routing Service
DECnet Routing Metric
DECnet Routing Metric
In both the level 1 and level 2 routing tables, the routing metric that is main-
tained is (path) cost. Each DECnet LAN and WAN has a cost value associ-
ated with it that relates to the speed of the link. Faster links have lower cost
values associated with them. To plan the cost assignments for a DECnet
internetwork and configure them on HP routers, see the "DECnet Link Cost"
section above.
The path cost is the cumulative cost value of the links along the path to the
destination node (in the level 1 routing table) or area (in the level 2 routing
table). For a given destination node or area, DECnet routing tables reflect
the least-cost path that the router has learned from periodically exchanging
routing update messages.
