hi,

man ip, the output about exit value is like following. "Exit status is 0 if command was successful, and 1 if there is a syntax error. If an error was reported by the kernel exit status is 2." Did the following COMMAND have syntax error? If not, should I still change the expected rc from 2 to 1?

hi,

I test ipv6_ping by "./fcnal-test.sh -v -t ipv6_ping". There are two tests failed.

TEST: ping out, VRF bind - ns-B IPv6 LLA [FAIL] TEST: ping out, VRF bind - multicast IP [FAIL]

While in fcnal-test.sh the expected command result is 2, the result is 1, so the test failed. ipv6_ping_vrf() { ...... for a in ${NSB_LINKIP6}%${VRF} ${MCAST}%${VRF} do log_start show_hint "Fails since VRF device does not support linklocal or multicast" run_cmd ${ping6} -c1 -w1 ${a} log_test_addr ${a} $? 2 "ping out, VRF bind" done

The ipv6_ping test output is attached.
Did I set something wrong result that these tests failed?

best regards,

ping6 is failing as it should. Can you send a patch to change the expected rc from 2 to 1?
