Bfd For Is-Is Configuration Example - HP 6125XLG Layer 3 - Ip Routing Configuration Manual

BFD for IS-IS configuration example

Network requirements
As shown in
•
at the network layer.
After the link over which Switch A and Switch B communicate through the Layer-2 switch fails, BFD
•
can quickly detect the failure and notify IS-IS of the failure. Switch A and Switch B then communicate
through Switch C.

Configuration procedure
1. Configure IP addresses for interfaces. (Details not shown.)
2. Configure basic IS-IS:
# Configure Switch A.
<SwitchA> system-view
[SwitchA] isis
[SwitchA-isis-1] network-entity 10.0000.0000.0001.00
[SwitchA-isis-1] quit
[SwitchA] interface vlan-interface 10
[SwitchA-Vlan-interface10] isis enable
[SwitchA-Vlan-interface10] quit
[SwitchA] interface vlan-interface 11
[SwitchA-Vlan-interface11] isis enable
[SwitchA-Vlan-interface11] quit
# Configure Switch B.
<SwitchB> system-view
[SwitchB] isis
[SwitchB-isis-1] network-entity 10.0000.0000.0002.00
[SwitchB-isis-1] quit
Figure 46, run IS-IS on Switch A, Switch B and Switch C so that can reach each other
