DECnet: Routers Not Establishing Adjacencies (continued)
Possible Problem
Solution
Adjacency
between routers is
not bidirectional
1.
Use the
show decnet route exec
command to see if the
adjacency with the expected designated router is in a “down”
or “initializing” state.
2.
If you are troubleshooting a nonbroadcast multiaccess
network (such as Frame Relay or X.25), make sure that
map
statements are properly configured.
To establish an address translation for selected nodes, use the
decnet map
global configuration command:
Syntax:
decnet
first-network
map
virtual-address second-network
real-address
•
first-network
—DECnet network numbers in the range 0 to 3.
•
virtual-address
—Numeric DECnet address (10.5, for
example).
•
second-network
—DECnet network number you map to;
DECnet numbers range 0 to 3.
Syntax Description:
real-address
—Numeric DECnet address (10.5, for
example).
•
Use the
debug decnet adj privileged exec
command to
determine whether hello packets are being exchanged.
3.
If a router is not sending hello packets, use the
show interfaces
command to determine whether the
interface input and output queues are full. A full input queue
is indicated by a value of 75/75, and a full output queue is
indicated by a value of 40/40.
4.
If the queues are full, and no hello packets are being
exchanged, contact your router technical support
representative.
