Usage guidelines
After hosts on the same link receive RA messages, they can use the prefix information in the RA
messages for stateless autoconfiguration.
Examples
# Configure the prefix information in RA messages on VLAN-interface 100.
Method 1:
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd ra prefix 2001:10::100/64 100 10
Method 2:
<Sysname> system-view
[Sysname] interface vlan-interface 100
[Sysname-Vlan-interface100] ipv6 nd ra prefix 2001:10::100 64 100 10
ipv6 nd ra router-lifetime
Use ipv6 nd ra router-lifetime to configure the router lifetime in RA messages.
Use undo ipv6 nd ra router-lifetime to restore the default.
Syntax
ipv6 nd ra router-lifetime value
undo ipv6 nd ra router-lifetime
Default
The router lifetime in RA messages is 1800 seconds.
Views

Parameters
value: Specifies the router lifetime in the range of 0 to 9000 seconds. If the value is set to 0, the router
does not serve as the default router.
Usage guidelines
The router lifetime in RA messages specifies how long the router sending the RA messages serves
as the default router. Hosts receiving the RA messages check this value to determine whether using
the sending router as the default router. If router lifetime is 0, the router cannot be used as the default
router.
