…you find chicken feet in the office fridge!
Went up to the peak again to show a friend around hong kong.
It’s a great spot except for the ‘congestion’ to get up there. If you go, try a week day, it’s a bit less crowded 
One of the most important things about building a network is making it scalable. The fact that it “works” now should never be an excuse for a poor design.
In BGP, there are several ways you can control routes that are received from or sent to a BGP neighbor, prefix lists, IP Access Lists and BGP Community tags.
All 3 are used and in different purposes in the ASN’s I administer.
In the past few months, I’ve seen a repeating occurrence with some ISP’s who have either a Prefix List or Access-List configured facing their upstreams and peers to control their customer and internal routes. This is a very bad idea.
A case I’ve come across today is pictured below.
Network Next Hop Metric LocPrf Weight Path *> 202.22.171.0 206.223.143.164 100 250 0 18221 4826 7606 9942 9942 9942 ? *> 202.22.174.0 206.223.143.164 100 250 0 18221 4826 7606 9942 9942 9942 ?

While this is not the only solution, it is by far the most scalable. One other option is to put an AS_PATH filter on your peers/upstreams, listing the neighbor ASN and denying it to be advertised.
While this works, its not a scalable option as when your network grows, you need to update all of the filters again for each new peer you make. It also doesn’t resolve the issue of lazy house keeping with turn ups/downs.
Please remember though, use of BGP Communities on their own can be dangerous also, as you don’t know what your customer might be sending you, so continue to use your prefix-lists/access-lists and AS_PATHs to help manage and protect your network, but consider the use of communities to track a routes origin and make sure you’re handling it correctly.
I am not an administrator of AS18221.
People with pets here are stuffed. They have huge dogs living in tiny places.
There really isn’t enough space here for large dogs, its so unfair on them!
I saw today something even worse. On the MTR, people were keeping their dog in a zipped bag!
The dog was panting like crazy – too hot in the bag. How can people treat their pets like this! 
Great bit of Chinese Engrish, or Chinglish, not to mention just hilarious to have at the urinal.
The Chinese translation is a little bit different I’m told. its closer to:
“Taking one step closer will be a big step for our culture.”
I tried Cafe de Coral for dinner last night. Its $1 cheaper than MX at $43.
The quality? Equal, though the pepper sauce was much better.
This is a new definition for the outhouse. Roofhouse?
Enjoy
After the success of ‘echoes of the rainbow’ set in 1960′s Hong Kong, Wing Lee street, where the movie is set, has become somewhat of a local tourist trap.
I went for a walk through to check it out as it’s one of the few older housing areas left in Hong Kong.
First thing I saw on the street was an old lady at the doorways to one of the houses. She seemed less than impressed with all the attention.
A large no photos sign was stuck on her place too. I decided not to take direct photos of the places there to respect them.
So what’s so special about Wing Lee street? Nothing that I can tell at first glance. The movie depected things much better than this dilapidated old street.
