Archived Results

Here are the results we obtained with TAHI conformance tests running on MIPL 2.0.

• The Linux distribution installed on NUT is Fedora Core 3.
• The most recent test results are listed first.
• The most recent run for each category (HA, MN, CN) has a colored background.

Analysis

17	HA_2_1_9 - Comparison of binding lifetime and prefix lifetime

217	HA_8_1_7 - Comparison of binding lifetime and prefix lifetime in Mobile Prefix Advertisement

220	HA_8_1_8 - Comparison of binding lifetime and prefix lifetime in Mobile Prefix Advertisement

Symptoms: MN couldn't get BA.
Notes:

• In fact, the MN receives a BA, but its status is 1 (accepted but prefix discovery is required) instead of 0 (accepted). This a problem in mip6d. Comparison between Binding Update Lifetime and Mobile Prefix Lifetime is bugged.
• See Issues page.
• Solved.

174	HA_5_1_7 - Relay ICMP error while using bi-directional tunnel

Symptoms: MN couldn't get Destination Unreachable.

1	CN-1-1 - Normal Test - Return Routability

Symptoms: CN doesn't reply to ICMP Echo Request.
Notes: Looks like a configuration problem.

9	MN-3-3-1-1-002 - Use the old router when the old router is reachable

Symptoms: HA0 receives Binding Update(Care-of Address NUTY).
Note:

• This test succeed without IPsec on snapshot 2006/02/01.
• This test also succeed with IPSec if the mip6d configuration contains the option: "MnRouterProbes 2;" instead of "MnRouterProbes 1;". (this was the only difference between ipsec and no-ipsec conf). Timing issue in TAHI?
• This is indeed a timing issue between TAHI and MIPL. Leaving MnRouterProbes to 1 and using the mip6d option MnRouterProbeTimeout solves the problem. Default value (1 sec) is too short for TAHI.
• There is a bug in MIPL: this option, MnRouterProbeTimeout, is not taken into account in md_probe_router().
• Solved

17	MN-2-1-1-1-013 - Retransmissions & Back off (Use InitialBindackTimeoutFirstReg as the initial retransmission timer)

Symptom: BU timeout period is not doubled upon each retransmission.

Note:

• This test passes when ran without DHAAD
• This test fails when DHAAD is enabled:
• This test executes as expected by TAHI until MAX_BINDACK_TIMEOUT is reached and BU retransmission in MN is lesser than MAX_CONSECUTIVE_RESENDS (5): BU are retransmitted as expected with the proper retransmission delay doubled after each resend.
• Once MAX_CONSECUTIVE_RESENDS is reached (6 BUs sent), MN restarts DHAAD to find another HA. The same HA answers to DHAAD requests. MN restarts home registration with the HA. TAHI HA receives this 7th BU and finds its retransmission delay is not doubled compared to previous BU (which is right because it is not the same registration session for the MN.)
• The question is: Is it conform if the MN restarts a Home Registration with the HA that failed to acknowledge its previous Home Registration session?

Symptoms: Could not get Destination Unreachable. Note: This test passes with TAHI 3.1.6. The test has been fixed in this release.

All tests passed.
We have not found a TAHI configuration that permit every test to pass in the same run.
Two configurations are needed to pass all tests:

1. To pass all the tests but 183, 184, 187 and 188 use: config.txt and mip6d.conf
   TAHI results
2. To pass 183, 184, 187 and 188 use: config.txt and mip6d.conf
