| TC04: VPP proxies valid ICMPv6 Neighbor Discovery request
| | [Documentation] |
| | ... | [Top] TG=DUT
| | ... | [Cfg] On DUT configure IPv6 addresses and neighbors, supress router\
| | ... | advertisement and configure IPv6 Neighbor Discovery proxy.
| | ... | [Ver] Make TG send a neighbor solicitation packet to it's other\
| | ... | interface through DUT, verify DUT responds to the packet instead\
| | ... | of forwarding it. Then exchange ICMPv6 Echo request/reply to verify\
| | ... | connectivity between interfaces.
