Enabling High Availability Features

RP is ACTIVE, standby ready, bulk sync complete

NSF interval timer expired (NSF restart enabled)

Checkpointing enabled, no errors

Local state:ACTIVE, Peer state:STANDBY HOT, Mode:SSO

The following display shows sample output for the Cisco configuration on the standby RSP. In this example, note the presence of “NSF restart enabled”:

 

 

Router# show isis nsf

 

 

NSF enabled, mode 'cisco'

 

 

RP is STANDBY, chkpt msg receive count:ADJ 2, LSP 7

 

 

NSF interval timer notification received (NSF restart enabled)

 

 

Checkpointing enabled, no errors

 

 

Local state:STANDBY HOT, Peer state:ACTIVE, Mode:SSO

 

Step 3

If the NSF configuration is set to ietf, use the show isis nsf command to verify that NSF is enabled on

 

 

the device. The following display shows sample output for the IETF IS-IS configuration on the

 

 

networking device:
