Description john.r.king 2001-01-16 14:30:01 UTC

I am trying to add an entry to the neighbour discovery table using ndp. The command I am using is:
ndp -s aaaa:bbbb:cccc:dddd:eeee:ffff:8492:a829 0:90:27:9f:c9:2d

Each time I try I get the same error message:
cannot intuit interface index and type for aaaa:bbbb:cccc:dddd:eeee:ffff:8492:a829

I have even added an entry into the routing table to indicate the interface for that prefix but this does not seem to help. The entry from netstat -rn reads:

aaaa:bbbb:cccc:dddd:eeee:ffff::/96 2001:618:5:0:290:27ff:fe9f:c92d UGSc fxp1

How-To-Repeat: Run the command:

ndp -s aaaa:bbbb:cccc:dddd:eeee:ffff:8492:a829 0:90:27:9f:c9:2d

Error message is given on each occasion

sumikawa is Mr KAME, particularly ndp.c. :^)

For making static ndp entry, direct routes must be exist like the below:

% uname -a
FreeBSD prince.don.to 4.9-STABLE FreeBSD 4.9-STABLE #18: Sat Nov  8 16:45:46 GMT 2003     sumikawa@prince.don.to:/usr/local/src/4-stable/src/sys/compile/SUMIKAWA  i386

fe80::1%lo0                     (incomplete)         lo0 permanent R      
fe80::2bd:bdff:fe07:1%vmnet1    0:bd:bd:7:0:1     vmnet1 permanent R      

You can see same error in IPv4:

%arp -s 1.1.1.1 0:90:27:9f:c9:2d
cannot intuit interface index and type for 1.1.1.1

My conclusion: This is spec, not bug.

Can I close this PR?

I forgot to say sorry for keeping open your PR for more than two years.
