ipv6 nd ra ns-interval
Syntax
ipv6 nd ra ns-interval [1000 - 4294967295|unspecified]
Description
Used on VLAN or tunnel interfaces to advertise the period (retransmit timer) in milliseconds between ND solicitations sent by a host for an unresolved destination, or between DAD neighbor solicitation requests. Increasing this setting is indicated where neighbor solicitation retries or failures are occurring, or in a "slow" (WAN) network.
Options
1000 - 4294967295An advertised setting in this range replaces the corresponding, locally configured setting in hosts on the VLAN.
unspecifiedSets the retransmit timer value in RAs to zero, which causes the hosts on the VLAN or tunnel to use their own locally configured NS-interval settings instead of using the value received in the RAs.
Specifiers
Default: unspecified (0) ; Range: 1000 - 4294967295 ms
Usage
The no form returns the setting
to its default.
This is the retransmit timer advertised as a
host-specific variable. It is separate from the retransmit timer used
by the routing switch for its own ND solicitations (ipv6
nd ns-interval).
If multiple routers on the same VLAN or tunnel
are configured to advertise an ns-interval (retransmit
time), all such routers should use the same NS-interval setting.
The default NS-interval setting for IPv6 host operation on E devices is 1000 ms. When the above command is used with the unspecified option to configure RAs, host devices configured by using the RA maintain their preconfigured NS-interval settings.
