DECnet: Connections to DEC Hosts Fail over Router (Router Problem)
Possible Problem
Solution
DECnet is not
enabled on router
Use the
show decnet interface privileged exec
command to
see on which interfaces, if any, DECnet is enabled.
1.
If the output shows that DECnet is not enabled, use the
show
running-config privileged exec
command to view the
router configuration. Determine whether DECnet global and
interface command specifications are configured on the
router.
2.
Enable DECnet routing on the appropriate routers and
interfaces. For detailed information on configuring DECnet,
refer to the Cisco IOS
Network Protocols Configuration
Guide, Part 2
.

Missing
decnet
cost
command
1.
Make sure that there is a cost configured on DECnet
interfaces. Check the configuration for a
decnet cost
cost-value
interface configuration command entry.
2.
If the command is not present, add the
decnet cost
command
for each interface on which DECnet is enabled.
End nodes and
router area
number mismatch
Check the configuration of end nodes and routers on the
network segment. Check the area address specified on end
nodes and routers.
1.
If an end node is not in the same area as a router on the
segment, you must either change the address of the end node
to be the same as a router on the segment, or you must
reconfigure a router on the segment with the same area
number as the end node.
2.
Actual cost to the
destination area is
more than the
configured cost
1.
Use the
show decnet interface exec
command to determine
the configured maximum cost to the destination area.
2.
Use the
show decnet route exec
command to determine the
actual cost to the destination area.
3.
If the actual cost is more than the configured maximum cost,
increase the maximum cost configured on the router.
On Level 1 routers, use the
decnet max-cost
global
configuration command to increase the area maximum cost.
On Level 2 routers, use the
decnet area-max-cost
global
configuration command to increase the area maximum cost.
