frame specified in seconds parameter.

link-local-address
Syntax link-local-address ipv6-address [preferred]
Context config>router>if>ipv6
config>service>ies>if>ipv6
config>service>vprn>if>ipv6
Description This command configures the IPv6 link local address.
The no form of the command removes the configured link local address, and the router automatically
generates a default link local address.
Removing a manually configured link local address may impact routing protocols or static routes that
have a dependency on that address. It is not recommended to remove a link local address when there
are active IPv6 subscriber hosts on an IES or VPRN interface.
Parameters preferred — Disables duplicated address detection and sets the address to preferred, even if there
is a duplicate address.
local-proxy-nd
Syntax [no] local-proxy-nd
Context config>router>if>ipv6
Description This command enables local proxy neighbor discovery on the interface.
The no form of the command disables local proxy neighbor discovery.
neighbor
Syntax neighbor [ipv6-address] [mac-address]
