DECnet: Routers Not Establishing Adjacencies
Possible Problem
Solution
More than 32
routers on the
network
DECnet limits the number of adjacencies that can be established
by a router to 32.
1.
Enable the
debug decnet events privileged exec
command
to determine whether the adjacency is being rejected. Enable
this command on one router at a time.
Caution:
Because debugging output is assigned high priority in
the CPU process, it can render the system unusable. For this
reason, use
debug
commands only to troubleshoot specific
problems or during troubleshooting sessions with Cisco
technical support staff. Moreover, it is best to use
debug
commands during periods of lower network traffic and fewer
users. Debugging during these periods decreases the likelihood
that increased
debug
command processing overhead will affect
system use.
2.
If the adjacency is being rejected, reduce the number of
adjacent routers or increase the priority of a router that you
want to be adjacent so that it has a higher priority than one
of the other neighboring routers. An adjacency will be
established with the router you want instead of with a router
assigned a lower priority.
Syntax:
The following is the syntax to adjust the priority of a router:
decnet router-priority
value
To elect a designated router to which packets will be sent when
no destination is specified, use the
decnet router-priority
interface configuration command.
Syntax Description:
value
—Priority of the router. This can be a number in the
range 0 through 127. The larger the number, the higher the
priority. The default priority is 64.
