Graceful Restart Mechanism For Several Commonly Used Protocols - 3Com S7906E Configuration Manual

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 protocols supporting IPv6, such as MPLS Label
Distribution Protocol (MPLS LDP), MPLS with Resource Reservation Protocol Traffic Engineering
(MPLS RSVP-TE), Border Gateway Protocol (BGP), Intermediate System to Intermediate System
(IS-IS), Open Shortest Path First (OSPF), and OSPFv3.
For the implementation and configuration procedure of the Graceful Restart mechanism of the above
protocols, refer to the related manuals in the IP Routing Volume and MPLS Basics and MPLS TE
Configuration in the MPLS Volume.
