An administrator is managing a network comprised of AOS-CX switches deployed at the aggregation layer. The switches are paired in a VSX stack and run the
OSPF routing protocol. The administrator is concerned about how long it takes for OSPF to converge when one of the VSX switches has to reboot.
What should the administrator to do speed up the OSPF convergence of the switch that is rebooting?
To speed up OSPF convergence when one of the VSX switches reboots, the administrator should implement graceful restart on the VSX switches and their neighboring OSPF switches. Graceful restart facilitates the continuation of forwarding traffic while re-establishing OSPF adjacencies, thus minimizing the OSPF downtime and speeding up convergence during the reboot process.
Graceful restart is correct
Page 419 Study Guide: failure of the VSF master or VRRP master could still disrupt routing and connectivity. OSPF graceful restart ensures nonstop routing as the standby member takes over as the master. [Aruba Networks]
