Usage
Information
Before you enable IPsec encryption on an OSPFv3 interface, first enable IPv6
unicast routing globally, configure an IPv6 address and enable OSPFv3 on the
interface, and assign the interface to an area.
An SPI value must be unique to one IPsec security policy (authentication or
encryption) on the router. Configure the same encryption policy (same SPI and key)
on each OSPFv3 interface in a link.
ipv6 ospf graceful-restart helper-reject
Configure an OSPFv3 interface to not act upon the Grace LSAs that it receives from a restarting OSPFv3
neighbor.
Syntax
ipv6 ospf graceful-restart helper-reject
To disable the helper-reject role, use the
no ipv6 ospf graceful-restart
helper-reject
command.
Defaults
The helper-reject role is not configured.

Version 9.2(0.0)
Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Command
By default, OSPFv3 graceful restart is disabled and functions only in a helper role to
help restarting neighbor routers in their graceful restarts when it receives a Grace
LSA.
When configured in a helper-reject role, an OSPFv3 router ignores the Grace LSAs
that it receives from a restarting OSPFv3 neighbor.
The graceful-restart role command is not supported in OSPFv3. When you enable
the helper-reject role on an interface, you reconfigure an OSPFv3 router to
function in a “restarting-only” role.
ipv6 ospf hello-interval
Specify the time interval between the hello packets sent on the interface.
Syntax
ipv6 ospf hello—interval
seconds
Parameters
seconds
Enter the time interval in seconds as the time between hello
packets. The range is from 1 to 65525 seconds.
