From: selias Date: Tue, 15 Aug 2017 17:33:50 +0000 (+0200) Subject: CSIT-775 HC Test: CRUD over IPv6 control-plane interface X-Git-Url: https://gerrit.fd.io/r/gitweb?p=csit.git;a=commitdiff_plain;h=442a2a7b0dfd2f1cd5a4ba03fb91ed32c96f8965 CSIT-775 HC Test: CRUD over IPv6 control-plane interface Adds new test suite which accesses Honeycomb's Restconf and Netconf northbound over IPv6. This is done by sending the requests to TG where an IPv4 to IPv6 tunnel is configured to the Honeycomb DUT.
