Configuring ISIS properties on an interface
29
NOTE
If you change the IS-IS type on an individual interface, the type you specify must also be specified
globally. For example, if you globally set the type to Level-2 only, you cannot set the type on an
individual interface to Level-1. The software accepts the setting but the setting does not take effect.
To change the IS-IS type on a specific interface, enter commands such as the following.
BigIron RX(config)# interface ethernet 2/8
BigIron RX(config-if-e1000-2/8)# isis circuit-type level-1
Syntax: [no] isis circuit-type level-1 | level-1-2 | level-2
The level-1 | level-1-2 | level-2 parameter specifies the IS-IS type. If you want to re-enable support
for both IS-IS types, re-enter the command you entered to change the IS-IS type, and use “no” in
front of the command.
Disabling and enabling hello padding on an interface
The section
“Globally disabling or re-enabling hello padding”
on page 891 explains what hello
padding is, why it is important and how to globally disable or enable it on a device. You can also
disable hello padding on a specific interface by entering commands such as the following.
BigIron RX(config)# interface ethernet 2/8
BigIron RX(config-if-e1000-2/8)# no isis hello padding
Syntax: [no] isis hello padding
By default, hello padding is enabled. Enter the no form of the command to disable hello padding.
Changing the hello interval
The hello interval controls how often an IS-IS interface sends hello messages to its IS-IS neighbors.
The default interval is 10 seconds for Level-1 and Level-2. You can change the hello interval for one
or both levels to a value from 1 – 65535 seconds.
To change the hello interval 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-interval 20
This command changes the hello interval to 20 seconds. By default, the change applies to both
Level-1 and Level-2.
Syntax: [no] isis hello-interval
<num>
[level-1 | level-2]
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.
