Configuring Generalized TTL Security Mechanism (GTSM) for OSPF
This task explains how to set the security time-to-live mechanism on an interface for GTSM.
SUMMARY STEPS
1. configure
2. router ospf process-name
3. router-id { router-id }
4. log adjacency changes [ detail | disable ]
5. nsf { cisco [ enforce global ] | ietf [ helper disable ]}
6. timers throttle spf spf-start spf-hold spf-max-wait
