The configurations of SwitchB and SwitchC are similar to the configuration of SwitchA, and
are not mentioned here.
Step 3 Configure the basic IS-IS functions.
# Configure Switch A.
[SwitchA] isis
[SwitchA-isis-1] is-level level-2
[SwitchA-isis-1] network-entity 10.0000.0000.0001.00
[SwitchA-isis-1] quit
[SwitchA] interface vlanif 10
[SwitchA-Vlanif10] isis enable 1
[SwitchA-Vlanif10] quit
[SwitchA] interface vlanif 20
[SwitchA-Vlanif20] isis enable 1
[SwitchA-Vlanif20] quit
# Configure Switch B.
[SwitchB] isis
[SwitchB-isis-1] is-level level-2
[SwitchB-isis-1] network-entity 10.0000.0000.0002.00
[SwitchB-isis-1] quit
[SwitchB] interface vlanif 50
[SwitchB-Vlanif50] isis enable 1
[SwitchB-Vlanif50] quit
[SwitchB] interface vlanif 20
[SwitchB-Vlanif20] isis enable 1
[SwitchB-Vlanif20] quit
[SwitchB] interface vlanif 40
[SwitchB-Vlanif40] isis enable 1
[SwitchB-Vlanif40] quit
# Configure Switch C.
[SwitchC] isis
[SwitchC-isis-1] is-level level-2
[SwitchC-isis-1] network-entity 10.0000.0000.0003.00
[SwitchC-isis-1] quit
[SwitchC] interface vlanif 10
[SwitchC-Vlanif10] isis enable 1
[SwitchC-Vlanif10] quit
[SwitchC] interface vlanif 50
[SwitchC-Vlanif50] isis enable 1
[SwitchC-Vlanif50] quit
# After the preceding configurations are complete, use the display isis peer command. You can
view that the neighboring relationship is set up between Switch A and Switch B, and that between
Switch A and Switch C. Take the configuration on Switch A as an example:
[SwitchA] display isis peer

Total Peer(s): 2
# The switches have learned routes of each other. Take the routing table of Switch A as an
example:
[SwitchA] display ip routing-table
Route Flags: R - relay, D - download to fib
