IPv6 Non stop routing and graceful restart
Syntax: [no] graceful-restart ipv6 protocols-converge-timer convergence-interval
The hold-time variable is the maximum hold time in seconds before management routing modules
sync up new forwarding information to interface modules during restart. The range of permissible
values is 0 to 1200 seconds. The default value is 5 seconds.
Configuring NSR and graceful restart on OSPFv3
OSPFv3 supports nonstop routing and graceful-restart helper mode. Nonstop routing and
graceful-restart helper mode can be configured both in legacy router mode or VRF mode. The
following commands are used to configure NSR and graceful-restart helper mode.
Brocade(config-ospf6-router)#nononstop-routing
Syntax: [no] nonstop-routing
The nonstop routing command enables nonstop routing in OSPFv3.
NSR OSPFv3 is only supported on Brocade MLX series and Brocade NetIron XMR devices. Graceful
restart helper mode is supported on Brocade MLX series and Brocade NetIron XMR devices and
Brocade NetIron CER and Brocade NetIron CES devices.
Use the graceful-restart helper command to configure or disable helper mode.
Brocade(config-ospf6-router)#graceful-restart helper
Syntax: [no] graceful-restart helper [disable | strict-lsa-checking]
The graceful-restart helper disable command disables the graceful-restart helper capability. By
default it is enabled.
The strict-las-checking command exits helper mode upon a change in topology during a graceful
restart.
