When vRtrIfIcmpV6Redirects is set to 'true', ICMPv6 redirects are
generated when routes are not optimal on this router and another
router on the same subnetwork has a better route in order to
alert that node that a better route is available. When
vRtrIfIcmpV6Redirects is set to 'false', ICMPv6 redirects are not
generated.
