Routing
Transmit Delay
The Transmit Delay parameter sets the time period before transmitting the
LSA. The default value is 1 second.
Cost
The Cost setting represents the link cost for the specified interface. This value is
embedded in the router’s LSA metric field and used for SPF calculation.
Default value is 65535. Range is 1-65535.
Hello Interval
The Hello Interval parameter is the timer value for sending the Hello packet on
the specified interface. This is a periodic handshake and ‘keepalive’ message
that establishes and tests the link up/down status to determine neighbor reach-
ability.
Default value is 10 seconds. Range is 1-65535.
Topology
The Topology parameter identifies the network type for the specified interface,
Star or Mesh. Note that this setting is only applicable to Hub routers; therefore,
this field only appears when the Working Mode is set to either Vipersat Hub or
Multipoint Hub.
In Star mode, route changes at each Remote are only updated in the Hub. In
Mesh mode, route changes at each Remote are updated in the Hub as well as
distributed to all of the other Remotes.
Caution: Setting the Topology for Mesh may require a larger number of routes,
with the possibility of exceeding the limit of 270 total routes per
modem/router.
Priority
The higher the value for this setting, the more eligible the router will be to
become the Designated Router. The Priority is also used for determining a
Backup Designated Router. A value of zero (0) eliminates the router from being
eligible for the DR or the BDR.
Default value is 1. Range is 0-255.
Dead Interval
The Dead Interval parameter is a timer value used for specifying the period
after which a non-responding neighbor is considered dead. Note that this setting
must be the same for all routers attached to a common network.
