The set protocols vrrp interface vrid ipv6-nd ra-fast-retrans command can be used to enable or disable IPv6 nd ra-fast-retrans.

The delete protocols vrrp interface vrid ipv6-nd ra-fast-retrans command restores the default configuration.

Command Syntax

set protocols vrrp interface <interface-name> vrid <virtual-router-id> ipv6-nd ra-fast-retrans <true | false>

Parameter

Parameter	Description
interface <interface-name>	Specifies the Layer 3 interface name of VRRP device. The value could be the VLAN interface name, the routed interface or the sub-interface name. The value is a string.
vrid <virtual-router-id>	Specifies the VRID of a VRRP group. The value is an integer that ranges from 1 to 254.
ra-fast-retrans <true \| false>	Enable or disable IPv6 nd ra-fast-retrans. true: Enable IPv6 nd ra-fast-retrans. false: Disable IPv6 nd ra-fast-retrans. By default, IPv6 nd ra-fast-retrans is enabled.

Usage Guidelines

RFC4861 states that consecutive RA packets should be sent no more frequently than three seconds apart. FRR by default allows faster transmissions of RA packets in order to speed convergence and neighbor establishment, particularly for unnumbered peering. By turning off ipv6 nd ra-fast-retrans, the implementation is compliant with the RFC at the cost of slower convergence and neighbor establishment.

Example

Disable IPv6 nd ra-fast-retrans.
