7.12.3 Configuring IPv6 IS-IS Interfaces
To configure an interface on an IS-IS device to send Hello packets or flood LSPs, IS-IS must
be enabled on this interface.
Context
The level of an IS-IS device and level of an interface together determine the level of a neighbor
relationship. By default, Level-1 and Level-2 neighbor relationships will be established between
two Level-1-2 devices. If only one level of neighbor relationships is required, you can configure
the level of an interface to prevent the establishment of the other level of neighbor relationships.
After IS-IS is enabled on an interface, the interface will automatically send Hello packets,
attempting to establish neighbor relationships. If a peer device is not an IS-IS device or if an
interface is not expected to send Hello packets, suppress the interface. Then this interface only
advertises routes of the network segment where the interface resides, but does not send Hello
packets. This suppression improves the link bandwidth usage.
Procedure
l
Issue 02 (2014-09-30)
IS-IS dynamic host name mapping is configured. The system ID of the local device
is mapped to the specified host name.
The value of symbolic-name is contained in LSP packets and advertised to other IS-
IS devices.
On another IS-IS device displays the value of symbolic-name, but not the system ID,
of the local IS-IS device.
2.
Run:
is-name map system-id symbolic-name
IS-IS static host name mapping is configured. The system ID of a peer IS-IS device
is mapped to the specified host name.
This command configuration takes effect only on the local IS-IS device. The value of
symbolic-name will not be added to LSP packets.
If dynamic host name mappings is configured on an IS-IS network, the mappings on
the network overwrite the mappings configured on the local router.
(Optional) Enable the output of the IS-IS adjacency status.
1.
Run:
log-peer-change
The output of the adjacency status is enabled.
(Optional) Enable IS-IS adjacency strict-check.
1.
Run:
adjacency-strict-check enable
IS-IS adjacency strict-check is enabled.
Configure an IS-IS interface.
