Description

It seems that I fail to create an ipv6 face to a remote host. ( I have a successful ping6 to this host)
I have two different issues here:

First: failure when I use tcp6, not sure why -
can we add an explanation here? In this case, can we output the next error: Connect to remote endpoint failed: Invalid argument

$build/bin/nfdc create tcp6://[fe80::d6ae:52ff:fecd:260c]

ERROR: Face creation failed: Failed to create face

No errors in the nfd log, but this is the info output (I filtered out the DEBUG messages to get a shorter log here):

NOT A BUG.

You can't use a link-local IPv6 address. Use a global-scope or site-scope address instead.

NFD Management doesn't support "link-local-address%iface" syntax.
If you want that, report another bug.

2 questions:

  1. So the crash I reported on is an intended assert?
  2. For now, I don't have any other way to test tcp6/udp6 without using link-local-address face. If you believe it's important for the current phase, I can open another bug. Any advice?

NFD should never crash after initialization. UDP crashing is reported as Bug #1427.

If you want link-local-address%iface support, open another bug.
