Item Description
Syntax [no] ipv6 
Context configure>service>ies>interface
Description This command configures an IPv6 interface.
Note —  When IPv6 routing is configured on the IHub and an 
iBridge is configured on the LT board, it is not possible to obtain 
a DHCPv6 lease when IPv6 multicast control is disabled on the 
LT board. This is due to the fact that the NT board requires 
adding the <IPv6, MAC> information in the Neighbor Cache by 
sending a downstream multicast Neighbor Solicitation 
message. If IPv6 multicast control is disabled on the LT board, 
such messages are discarded and the DHCPv6 connection 
cannot 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 FX 
NT  for more information
