This parametermust be specified with the seconds parameter.Values: 10 — 1000seconds — The time frame in seconds used to limit the number of ICMP unreachablemessages that can be issued.Values: 1 — 60Item Description(2 of 2)Item DescriptionSyntax [no] ipv6Context configure>service>vprn>interfaceDescription This command configures an IPv6 interface.Note — When IPv6 routing is configured on the IHub and aniBridge is configured on the LT board, it is not possible to obtaina DHCPv6 lease when IPv6 multicast control is disabled on theLT board. This is due to the fact that the NT board requiresadding the information in the Neighbour Cacheby sending a downstream multicast Neighbour Solicitationmessage. If IPv6 multicast control is disabled on the LT board,such messages are discarded and the DHCPv6 connectioncannot be established. To allow IPv6 routing to work correctly,IPv6 multicast control needs to be allowed on the LT board.See the CLI Command Guide for FD 100/320Gbps NT and FXNT for more information
