Supported IS-IS features
Multiple instances and processes
IS-IS supports multiple instances and processes. Multiple processes allow an IS-IS process to work
in concert with a group of interfaces. A router can run multiple IS-IS processes, and each process
corresponds to a unique group of interfaces.
For routers supporting VPN, each IS-IS process is associated with a VPN instance, which means the
VPN instance is also associated with interfaces of the process.
Active/Standby failover
In standalone mode, IS-IS backs up necessary data from the active MPU to the standby MPU.
Whenever the active MPU is down, the standby MPU can switch to the active status to run IS-IS.
In IRF mode, IS-IS backs up necessary data from the global active MPU to the global standby MPU.
Whenever the global active MPU is down, the global standby MPU can switch to the active status to
run IS-IS.
IS-IS supports the Graceful Restart (GR) backup mode:
•
In standalone mode, GR backs up only the configuration of IS-IS. After active/standby MPU
failover, IS-IS performs graceful restart to synchronize the LSDB with neighbors.
•
In IRF mode, GR backs up only the configuration of IS-IS. After global active/standby MPU
failover, IS-IS performs graceful restart to synchronize the LSDB with neighbors.
IS-IS GR
GR ensures the continuity of packet forwarding when a routing protocol restarts, an active/standby
MPU switchover in standalone mode occurs, or a global active/standby MPU switchover in IRF mode
occurs.
•
GR restarter—Graceful restarting router. It must be GR capable.
