Configuring IPv4 address family route parameters
29
This command disables all hello PDU padding on the device. To re-enable padding, enter the
following command.
BigIron RX(config-isis-router)# hello padding
Syntax: [no] hello padding
By default, hello padding is enabled. Enter the no form of the command to disable hello padding.
To disable hello padding on an interface, refer to “Disabling and enabling hello padding on an
interface” on page 967.
Logging adjacency changes
The device can generate a Syslog entry and an SNMP trap to indicate a change in the status of
an adjacency with another IS. Logging of the adjacency changes is disabled by default. To enable or
disable them, use either of the following methods.
To enable logging of adjacency changes, enter the following command.
BigIron RX(config-isis-router)# log-adjacency-changes
Syntax: [no] log-adjacency-changes
To disable logging of adjacency changes, enter the following command.
BigIron RX(config-isis-router)# no log-adjacency-changes
Configuring IPv4 address family route parameters
This section describes how to modify the IS-IS parameters for the IS-IS IPv4 unicast address family.
To enter the IPv4 unicast address family, refer to
“Address family configuration level” on page 950.
Changing the metric style
The metric style specifies the Types, Lengths, and Values (TLVs) an IS-IS LSP can have. The TLVs
specify the types of data, the maximum length of the data, and the valid values for the data. One of
the types of data the TLVs control is a route’s default-metric. By default, the device uses the
standard IS-IS TLVs, which allows metric values from 1 – 63. The default metric style is called
“narrow”. You can increase the range of metric values supported by the device by changing the
metric style to wide. The wide metric style allows metric values from 1 – 16777215.
To change the metric style to wide, enter the following command.
BigIron RX(config-isis-router-ipv4)# metric-style wide
This command changes the metric style for both Level-1 and Level-2.
Syntax: [no] metric-style wide [level-1 | level-2]
The level-1 | level-2 parameter specifies the levels to which the change applies. If not specified, the
changes are applied to both levels.
