The sum of maximum routers over all circuits should be less than
the executor maximum broadcast routers argument, although this
limit is not strongly enforced.
recall timer
Determines the delay in seconds between call attempts to establish
an X.25 outgoing static circuit.
For define, valid values are in the range 1 to 60 seconds. The
default is 1 second. See also the argument maximum recalls.
For set, valid values are in the range 0 to 65595 seconds. The
default is 60 seconds.
router priority [range]
Specifies the router’s priority in bidding to become the designated
router for the end-nodes on this circuit. Range: 1 to 127, where 127
is the highest priority. Default: 64.
If two routers have the same priority, the one with the higher node
address wins. The router priority has no effect on area routing
decisions, or in reaching the closest attached level 2 router.
Use the router priority to choose the designated router to be the
one that is most likely to be the best next hop for the end-nodes on
the circuit. If there are two routers on a circuit, one with 500 nodes
behind it, the other with 20 nodes behind it, the one with 500 nodes
should have the higher router priority. This is not required, however,
because once a packet from an end-node packet reaches a router,
it will be forwarded toward its destination.
This argument is irrelevant on point-to-point lines, where there will
be no end-nodes. (A designated router is selected anyway.)
router type
Specifies the kind of routing that the router needs to perform,
standard, AMA, or bilingual.
-
Standard
. Specifies that the router is using conventional phase IV
addressing where the MAC address is built from the area and node
number. The router defaults to this type.
-
AMA
. Specifies that the router can route packets that use phase
IV addressing where the MAC address is arbitrary and learned from
the data link layer.
-
Bilingual
. Specifies that the router can route packets that use both
conventional and phase IV with AMA addressing.
state When set to on specifies that the circuit is enabled for use by DNA.
When set to off specifies that the circuit is disabled for use by DNA.
off is the default.
usage Specifies whether an X.25 circuit is:
v PVC: A permanent virtual circuit
v OUT-SVC: An outgoing static circuit
v IN-SVC: An incoming static circuit
This parameter applies when the executor type is set to
DEC-routing-IV
or
DEC-area
. (See circuit executor type for
more information.)
