DECnet Routing Service
DECnet Link Cost
N o t e :
When the DECnet routing service is enabled on HP routers, the station
address will be modified, as described above, on all interfaces, even
those where DECnet routing service is not enabled. This "DEC" station
address will become the node ID for the router for IPX and XNS routing
services. It takes precedence over an XNS node ID that you may have
configured. An exception is on synchronous pass-through interfaces
where the "Local LAN Address" that you configure will take precedence
only on the pass-through interface.
DECnet Link Cost
DECnet network links are not assigned addresses. Instead, each link must
have a cost value associated with it. Ideally, the cost value should reflect the
speed of the link. The router uses this information to select the fastest (least-
cost) path to a destination. Therefore, cost values have a significant effect
on what routing decisions are made by the router.
Planning a DECnet internetwork involves determining the cost value for
each link. These values should be documented on the network map and
noted on the site survey worksheets. To configure link costs on HP routers,
use the Configuration Editor. Quick Configuration will assign the default
value if no other value has been previously configured. A table of recom-
mended values as well as a the default cost value, "Suggested DECnet
Circuit Costs", is in the DECnet chapter in the reference manual.
