Configuration Considerations for IPv6 Prefix Suppress
The following considerations should be considered prior to configuring IPv6 Prefix Suppress:
• Suppress option is not configurable for a non-existent IPv6 address entry. As a result, the
suppress option is not applicable to future references.
• Suppress option is not supported for suppressing prefix advertisement entries.
NOTE
The user may un-configure the prefix advertisement entry so it is not advertised in the RA
message.
• Configuration of the suppress option is not allowed for a duplicate entry in any
combination.
• When multiple IPv6 addresses of the same subnet are defined on an interface, apply the
suppress option on individual entries.
IPv6 ND Router Advertisement Control
IPv6 ND Router Advertisement Control allows for disabling sending out router advertisements at
the interface level. The no ipv6 nd suppress-ra command at the interface level allows the user to
disable and enable the sending of the ND Router Advertisement on an interface. By default, the
sending of ND Router Advertisement (RA) is enabled on all interfaces, except for the tunnel and
loopback interfaces, providing that the IPv6 Unicast Routing is enabled and the interfaces are
active for IPv6.
The IPv6 ND Router Advertisement Control gives the ability to quickly turn off the sending of IPv6
ND Router Advertisement message on an IPv6 enabled interfaces.
By default,
• The ND Router Advertisement is enabled.
• Interface is enabled to send ND Router Advertisements.
• The ipv6 nd suppress-ra and ipv6 nd send-ra interface commands, when configured, override
the system and VRF global ipv6 nd global-suppress-ra command.
