Richard,
There are several exchange points, but their functions tend to be slightly
different from what is understood in the US. IXes such as SOX (Singapore),
HKIX (Hong Kong), JPIX NSP-IXP2 (Japan) and KIX KINX (Korea) tend to be
the more oft quoted IXes in Asia and are familiar in design
All,
I have seen 6 portscans looking for SubSeven on a /24 in the past 24 hours.
It'd been a while since I had seen *any*, now I'm seeing all these. Is
this a new outbreak/vulnerability, or have I just been lucky? Has anybody
else seen an increase in scans on tcp port 27374?
I scanned

Don't forget that if both sites use the same as even if the connection
link drops they will not be able to see each other over the upstream
provider as routers won't take the srutes from the same as. If this
isn't a problem don't worry about it. If you wish to preserve
connectivity

This is a great solution to a point. I did this, with the help of
someone who reads this list frequently:) but you have to jump through
some hoops should you wish both cities to reach each other. Assuming
for example all your dns and mail servers are in one city you'd have to
jump
Interesting point there Scott.. we were discussing just that at a recent
IXP meeting I was at. Theres a number of different ways (well hacks) in
which you can keep connectivity between two halves of an AS network in the
event of a split.
Is anyone out there actually doing something either

* BGP is an EGP, not an IGP
BGP is one half of an IGP, it is the where to go half.
You generally run another IGP along with it to provide the
how to get there half. Most folks run isis or ospf to
transport router loopbacks and other next-hop
Actually I ran this way for a while as a primary. I had three sites
attached via cogent entirely all announcing a /19 and the internally a
/21 each and a couple /21's out of the primary location. In the main
location was a 7507 and in the two other pops 6509's. We set ospf

As it sounds like he's using a single AS, the above may not be
a fix, since a partitioned AS is still

BGP will discard any prefix with its own AS in the path, for loop

reach the other half. This is why a partitioned AS is a failure
condition. A tunnel is a means to keep the AS
isn't a problem don't worry about it. If you wish to preserve
connectivity between cities you should have a back-up link or use
different as's or gre tunnels:).
Floating statics would be a less-hassle means to continue connectivity
(with only 2 locations not much of a scaling issue).
