Which statements accurately describe OSPF Graceful Restart (when the restarting router is able to Keep its forwarding tables across the restart)? (Choose two.)
The correct answer is A. The GR helper role is supported on AOX-CX 6100 switches. D. OSPF Routers listen for Grace-LSAs on each network segment where there is an OSFP. Graceful Restart (GR) allows a router to continue forwarding packets while it restarts its OSPF process. The GR helper role on AOS-CX switches supports routers during this process. OSPF routers listen for Grace-LSAs to identify neighbors undergoing a graceful restart…
Question
Which statements accurately describe OSPF Graceful Restart (when the restarting router is able to Keep its forwarding tables across the restart)? (Choose two.)
Options
- AThe GR helper role is supported on AOX-CX 6100 switches.
- BVSF Failover and Graceful-Restart require a VSF secondary member in the VSF stack
- CBidirectional Forwarding Detection for OSPF and GR are mutually exclusive features.
- DOSPF Routers listen for Grace-LSAs on each network segment where there is an OSFP
- EYou must ensure your VSF stack has a secondary member when acting as a GR helper

Explanation
Graceful Restart (GR) allows a router to continue forwarding packets while it restarts its OSPF process. The GR helper role on AOS-CX switches supports routers during this process. OSPF routers listen for Grace-LSAs to identify neighbors undergoing a graceful restart, maintaining adjacencies with those routers to allow uninterrupted forwarding.
