RE: Traffic to our customer's address(126.0.0.0/8) seems blocked by packet filter
Hi,
Just out of curiosity... are you going to continue to announce each individual /16 or will you consolidate to a single /8 announcement? We aren't going to consolidate to a single /8 announcement. We are going to continue to announce each individual /16 for incoming traffic engineering.

Hi
Thank you for your reply.
Makoto san, can you provide an ip-address within your assigned range that people can ping to test? You can ping to 126.66.0.30/8.

The following address blocks were allocated from IANA to APNIC on the 27th of JAN of 2005. Please refer to the following link. http://www.cymru.com/Documents/bogon-list.html --- Changes in version 2.6 (27 JAN 2005) 124/8, 125/8 and 126/8 allocated to APNIC (JAN 2005). Removed from the bogon lists. ---
Softbank BB (AS17676) was allocated 126/8 from APNIC, and Softbank BB (AS17676) immediately tried to use 126/8. However Softbank BB could not access the famous site using 126/8, It seems some of ISPs are blocking 126/8 due to outdated filter.
Ladies and gentlemen, please check the following URL! http://www.cymru.com/Documents/bogon-list.html
and if you find out you have outdated filter, please update the filter immediately.
Please let me know if you have any problem, concern or doubt regarding opening a filter for 126/8, please let me know.

FWIW, if you don't announce your aggregate, do not be surprised if you experience continued disconnectivity to many parts of the Internet. Some SPs notice that SoftbankBB have received 126/8, so will likely filter as such. Leaking sub-prefixes may be fine for traffic engineering, but this generally only works best if you include a covering aggregate. Try including your /8 announcement and see if this improves reachability for you. Out of curiosity, why pick on a /16 for traffic engineering? Most people tend to analyse traffic flows and pick the appropriate address space size as a subdivision. Or do you have 256 links to upstream ISPs and need that level of fine-tuning? best wishes, philip --
