Dst_Unreach_3_Global.seq - check ICMPv6 Destination Unreachable code 3
Host and Router
Dst_Unreach_3_Global.seq [-tooloption ...] -p Dst_Unreach_3_Global.def
This test is OFF-LINK Network Configuration test. Physical Network configuration --------------------------------------- | | NUT TN
Logical Network Configuration
TN | ---------------------------------- | NUT | ---------------------------------- | OFFLINKA Host
When test stars, states of Neighbor Cache Entry for TN's addresses are reachable.
This test verifies that NUT sends valid ICMPv6 Destination Unreachable (code 3) in response to a packet which can not be delivered to destination address (e.g. Address Resolution in ND).
TN NUT
---------------------------
1. === Echo Request packet ===> src address : TN link local address dst address : NUT Link1 unreachable address 2. << JUDGMENT >>
<=== ICMPv6 Destination Unreachable === Code is 3
<< PASS >> NUT send ICMPv6 Destination Unreachable.
<< FAIL >> NUT do not send ICMPv6 Destination Unreachable.
