Helper
, the GR Restarter obtains the necessary topology and
routing information from all its neighbors through the GR sessions between them and
calculates its own routing table based on this information.
2.4 Graceful Restart Mechanism for Several Commonly Used
Protocols
The switch supports Graceful Restart for Boarder Gateway Protocol (BGP), Open
Shortest Path First (OSPF), and Intermediate System to Intermediate System (IS-IS).
For the implementation and configuration procedure of the Graceful Restart
mechanism of the above protocols, refer to
