714 Configuring IP routing on an interface
N0008589 3.3
6 Configure the RIP Parameters according to the following table.
Table 204 IP RIP Parameters
Attribute Description
Metric Allows you to assign a cumulative value (in terms of hop count or associated cost [if applicable])
to routes passing through this interface. The routing manager adds the metric value of all routes
learned through this interface to the metric value of this interface to make routing decisions. The
possible values are
1 to 16 .
Because RIP protocol can handle up to 15 hop counts before reaching destination, a value of 16
corresponds to “counting to infinity”.
The default value is
1 .
Routing Table
Update Mode Allows you to specify the routing table update mode. The possible values are:
On Demand: The router sends its table when another established router requests it.
Periodic : The router sends its table to other established router at regular intervals.
On dialup interfaces, you must set the Update Mode to Periodic to receive updates.
The default value is Periodic .
Route
Announcement
Type Allows you to set the type of routing table update announcements the Business Communications
Manager router sends to other routers.
The possible values are:
Disabled : disables sending RIP routing update. If you choose Disabled , you must configure the
other routers in the subnet to use static routes to access the Business Communications Manager
base unit.
RIP 1 : sends only announcements of RIP v1 type in broadcast mode.
RIP 1 Compatible : sends RIP v1 and RIP v2 packets in broadcast mode. Use this for a network
environment that uses RIP v1 and RIP v2.
RIP 2 : sends RIP v2 packets in multicast mode only. Use this type of announcement only if all
other routers connected to the Business Communications Manager base unit support RIP v2.
The default value is RIP 1 .
Route Accept
Type Allows you to set the type of routing table update announcements the Business Communications
Manager router accepts from other routers.
The possible values are:
Disabled : disables sending RIP routing table update announcements. If you choose Disabled ,
you must create static routes in the Business Communications Manager base unit to access
other networks connected to this interface. This method is preferable if you want to keep the
routing table small in the Business Communications Manager base unit.
RIP 1 : accepts only announcements of RIP 1 type.
RIP 1 Compatible : accepts announcements of RIP 1 and RIP 2 types.
RIP 2 : accepts announcements of RIP 2 type only.
The default value is RIP 1 .
Route Expiration
Interval Allows you to define the period of time within which a route in the routing table must be updated
to remain a valid route. The possible values are
15 to 259200 seconds .
The default value is 180 seconds.
Route Removal
Interval Allows you to define the period of time (in seconds) an invalid route remains in the routing table
before the routing manager removes it from the routing table. The possible values are
15 to
259200 seconds .
The default value is 120 seconds
Route
Announcement
Interval Allows you to set the time interval (in seconds) between routing table updates when the Routing
Table Update Mode is set to Periodic . The possible values are 5 to 86400 seconds.
The default value is 30 seconds.
