Restrictions for DHCPv6 Options Support
The following restrictions apply to the Lightweight DHCPv6 Relay Agent (LDRA) feature:
• An interface or port cannot be configured as both client facing and server facing at the same time.
• Access nodes implementing LDRA do not support IPv6 control or routing.
• Unlike a DHCPv6 relay agent, an LDRA does not implement any IPv6 control functions (like
Internet Control Message Protocol Version 6 [ICMPv6] functions), nor does it have any routing
capability in the node.
