Changing The Hello Multiplier; Changing The Metric Added To Advertised Routes - Dell PowerConnect B-RX Configuration Manual

The <num> parameter specifies the interval, and can be from 1 – 65535 seconds. The default is
10 seconds.
The level-1 | level-2 parameter applies the change to only the level you specify. If you do not use
this parameter, the change applies to both levels.

Changing the hello multiplier

The hello multiplier is the number by which an IS-IS interface multiplies the hello interval to obtain
the hold time for Level-1 and Level-2 IS-to-IS hello PDUs. The default multiplier is 3. You can set the
multiplier to a value from
3 – 1000.
To change the hello multiplier for Ethernet interface 2/8, enter commands such as the following.
BigIron RX(config)# interface ethernet 2/8
BigIron RX(config-if-e1000-2/8)# isis hello-multiplier 50
This command changes the hello interval to 50. By default, the change applies to both Level-1 and
Level-2.
Syntax: [no] isis hello-multiplier <num> [level-1 | level-2]
The <num> parameter specifies the multiplier, and can be from 3 – 1000. The default is 3.
The level-1 | level-2 parameter applies the change to only the level you specify. If you do not use
this parameter, the change applies to both levels.

Changing the metric added to advertised routes

When the device originates an IS-IS route or calculates a route, the device adds a metric (cost) to
the route. Each IS-IS interface has a separate metric value. The default is 10.
The device applies the interface-level metric to routes originated on the interface and also when
calculating routes. The device does not apply the metric to link-state information that the device
receives from one IS and floods to other ISs.
The default interface metric is 10. You can change the metric on an individual interface to a value
in one of the following ranges:
•
•
NOTE
If the metric value you want to use is higher than 63 but you have not changed the metric style to
wide, change the metric style first, then set the metric. The IS-IS neighbors that will receive the
advertisements also must be enabled to receive wide metrics.
To change the IS-IS metric on an interface, use the following CLI method.
BigIron RX(config)# interface ethernet 2/8
BigIron RX(config-if-e1000-2/8)# isis metric 15
Syntax: [no] isis metric <num> [level-1 | level-2]
The <num> parameter specifies the metric. The range of values you can specify depends on the
metric style. You can specify 1 – 63 for the narrow metric style or 1 – 16777215 for the wide metric
style. The default in either case is 10.
