Figure 1-4 The GR Restarter obtains topology and routing information from the GR Helper
As illustrated in
Figure 1-4
, 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.
Graceful Restart Mechanism for Several Commonly Used Protocols
Comware supports Graceful Restart based on Border Gateway Protocol (BGP), Open Shortest Path
First (OSPF), Intermediate System to Intermediate System (IS-IS).
For the implementation and configuration procedure of the Graceful Restart mechanism of the above
protocols, refer to BGP Configuration, OSPF Configuration, and IS-IS Configuration in the IP Routing
Volume.
