Displaying and
Debugging IS-IS
Typical Integrated IS-IS
Configuration Example
Resetting All the IS-IS Data Structure
When it is necessary to refresh some LSPs immediately, perform the following
configuration in user view..
Table 81 Resetting all the IS-IS Data Structures
Operation
Reset the IS-IS data structure
Resetting the Specified IS-IS Peer
When it is necessary to connect a specified peer again, perform the following
configuration in user view..
Table 82 Reset the Specified IS-IS Peer
Operation
Reset the specified IS-IS peer
Through the following configuration operations, you can view the LSDB of the
IS-IS, the transmitting/receiving of various packets of the IS-IS and the SPF
calculation to determine the IS-IS route maintenance conditions.
After the above configuration, execute the display command in all views to
display the running of the IS-IS configuration, and to verify the effect of the
configuration. Execute the debugging command in user view to debug the IS-IS
module..

As is shown in Figure 11, Switches A, B, C and D belong to the same autonomous
system. The IS-IS routing protocol is run in these four switches to implement route
interconnection. In network design, switches A, B, C and D belong to the same
area.
