HKIX Finding for the Incident on 9 April 2016

After further investigation, we found one ISP (not HKIX participant) advertised a more specific route 123.255.88.0/22 (HKIX peering LAN) via its upstream provider to the global Internet.  We have applied BGP filters on HKIX route servers so the improper route did not affect RS1 and RS2. However, many ISP routers learned this route from their upstream providers and used this improper route to HKIX.  As a result, their BGP sessions with multi-lateral / bi-lateral peering to HKIX was interrupted due to 123.255.88.0/22 was NOT routable to the Internet.

Regarding proxy ARP, it seems some HKIX participant routers would respond ARP request on 123.255.88.0/21 if they learned a specific route (i.e. 123.255.88.0/22) from other interfaces.  May we take this opportunity to remind all HKIX participants again to ensure that proxy ARP is DISABLED on your router interfaces at all times.

To prevent improper routes receiving by your routers, it is suggested ALL HKIX participants to filter out 123.255.88.0 – 123.255.95.255 (8 Class C) from your inbound and outbound BGP because this network is supposed for HKIX Peering LAN and should NOT routable to the global Internet.

9 Apr 2016 BGP Sessions with HKIX Found Flapping from 10:30-12:30 Apr 9, 2016

The BGP sessions between HKIX and several HKIX participants were found flapping at 10:30 Apr 9, 2016.

After investigation, we suspected a HKIX participant conducted its router interface re-configuration without proxy ARP DISABLED and causing some peering IP addresses binding to the its MAC address at the Route Servers’ ARP tables; which then caused the flapping.

The participant’s port was then shut down and the wrong ARP caches of both Route Servers were cleared; the BGP sessions returned normal at around 12:30 on Apr 9, 2016.

The participant’s port is currently put in a testing VLAN for joint investigation and we will only put its port back to the production VLAN when the problem/issue is completely solved.

I would also like to take this opportunity to remind all HKIX participants to ensure that proxy ARP is DISABLED on your router interface towards HKIX at all times.

Thanks for your attention.

Scheduled Maintenance for HKIX Route Servers on 10-Jan-2016 (Sunday) & 24-Jan-2016 (Sunday)

Date:

10-Jan-2016 (Sunday) & 24-Jan-2016 (Sunday)

Time Window:

0200 - 0800 HKT (UTC +8)

Maintenance:

Planned OS Upgrade on HKIX Route Servers

 

Impact:

OS Upgrade on HKIX Route Servers
There will be no impact to HKIX participants which have BGP sessions with both route servers RS1 (123.255.88.1/21 & 2001:7FA:0:1::CA28:A101/64) and RS2 (123.255.88.2/21 & 2001:7FA:0:1::CA28:A102/64). During the upgrade, your BGP sessions with one RS will be down but your BGP sessions with the another route server will NOT be affected and the multi-lateral peering can still be maintained.

If you have not set up BGP sessions with both RS1 and RS2, you should do it ASAP for better resilience.

Scheduled Maintenance for HKIX switches on 11-Oct-2015 (Sunday) & 25-Oct-2015 (Sunday)

Date:

11-Oct-2015 (Sunday) & 25-Oct-2015 (Sunday)

Time Window:

0300 - 0800 HKT (UTC +8)

Maintenance:

Planned OS Upgrade on HKIX switches

 

Impact:

OS Upgrade on HKIX Switches
HKIX will perform OS upgrade on HKIX switches and reload the Ethernet Modules one by one.  You may experience up/down events on your HKIX link(s) within 30 minutes during the module startup.  In normal situation, if you have multiple LACP links to HKIX, the links should be connected to different Ethernet Modules and the traffic will be forwarded by the rest of LACP links on the same switch.
