Philippines new Internet Exchange!

Philippine OpenIX will be the newest addition to Internet Exchanges here in the Philippine networking world.

Here are some details about this IX.

-Carrier-neutral IPv4 and IPv6 Multilateral Peering Exchange
-Non-profit Membership-based
-Open to all
-Layer 2 Exchange (supports 10/100/1000Base T interconnect)
-BGP Peering (member needs own ASN)
-Managed and operated by DOST-ASTI(research agency)
-Location at Innove MK2 Data Center (former Ayalaport), Pasay Road Extension, Makati City
-Supported by CICT, PHNOG, Innove, Cisco and PCH
-First come, first connect policy

More information can be found at
http://www.phopenix.net/

We are hoping that it would inevitably spur the growth of local content, local hosting and local traffic. This would mean better experience, more stable and cheaper since local traffic wouldn't pass through expensive upstreams. This is going to be a distant dream, but I hope someday we'll be something like South Korea.

Babelgum

Just joined the Babelgum beta testing for having a TV-like experience on your computer.

So far, there are only a small amount of content available for viewing, quality is ok but could be better specially on full-screen.

Running Cisco Catalyst?

We've stumbled upon a concern on our Cisco Catalyst 3750's and you may face the same dilemma too in the future especially on large networks. Cisco's 3750 has 12k mac-address support, yes based on the data sheet. This is not turned on by default, by default, maximum number of mac-address that you can have on a stack is 6k. Why is this?

Read on about SDM, Cisco's Switching Database Manager for the pro's and con's of each SDM template

Segway on another topic!

Another SDM, the Cisco Security Device Manager makes you control security aspects of your router or switch using a web utility, not my taste though. But you might like it. It's free by the way.

VPLS

If you are a network administrator, get ready to know VPLS

http://vpls.org/vpls_technical_overview.shtml

If Ethernet over MPLS is point to point, VPLS is multipoint and more. I am starting to like the flexibility of VPLS when I implement solutions for connectivity.

BBS

Something flew into my mind and thought if there are still some BBS's here in the Philippines today, and guess what, there still are!

I started out BBS when DOS was still the OS of the future hehe, running Windows 3.1 back then was expensive, because everything is expensive (the ram, the harddisk, the processor) even the pirated copy of Windows 95 OSR2 costs 800 pesos! damn!

When I bought my first 486dx2 pc, i also bought a 28.8 creative external modem, the fastest back then was 33.6kbps. Since there's no internet or it is very very expensive, I'll login to BBS or Bulletin Board Systems. Definition here. Here, I would download files, games, read mails (board only mails or fidonet/interboard mails). Since most will only let you login once a day and for only 30mins, you'll have to hop around BBS's. I used to hop around Livewire Manila, Hollywood BBS, The Filebank BBS, Cool Call BBS etc.

It is also the BBS where I got my very first email, if i may recall it was @filebankbbs.znn.com hrmm can't recall. It was were I first got an international electronic mail when my friend who went to China emailed me, being a newbie that I was, I was so excited hahaha.

So many stories about BBS's here in Metro Manila but can't tell them all here. Haay, from the long list of Joel Mique, now it's down to a small file, only a few lines left. Most "techie" nowadays may haven't even heard or have used a BBS, but then again, there's the internet already. Maybe BBS's are just for us sentimentals. Maybe you could login to a BBS here someday.

Some links:

Terminate 5 - http://www.terminate.com/download.htm This is what I use to connect to BBS's and prolly host a BBS for my friends to download files from my PC via xmodem protocol.

Why I hate Windows

Imagine yourself working late at night, working overtime. Then you'll be bugged by this message





Who cares about that font, for it to be considered as a critical update, shees, and windows is telling me I might have to reboot my computer for the update to take effect.

Windows crap!

What Is VRRP?

VRRP stands for Virtual Router Redunduncy Protocol, in the Cisco world, it's counterpart is the HSRP or Hot Standby Routing Protocol. I was addicted to HSRP, not knowing that it's Cisco only. Now, we'll standardize all redunduncy to VRRP so that we'll be vendor independent.

VRRP's configuration is much like HSRP's and based on my test, can go hand in hand with each other for a smoother transition.

Router A
interface gigabitethernet0/1
ip address x.x.x.3 x.x.x.x
vrrp 100 description Virtual IP for AccessNet
authentication text blah
vrrp 100 ip x.x.x.1
vrrp 100 priority 200
vrrp 100 preempt

Router B
interface gigabitethernet0/1
ip address x.x.x.4 x.x.x.x
vrrp 100 description Virtual IP for AccessNet
authentication text blah
vrrp 100 ip x.x.x.1
vrrp 100 priority 210
vrrp 100 preempt

The higher the priority value, the most prioritized and will be Master, the other will be on standby.

One lesson learned, if there's an IETF standard version, use it!

SWIDB Limit?

Got this error:

%INTERFACE_API-1-NOMORESWIDB: No more SWIDB can be allocated, maximum allowed 20050
-Traceback= 6076CE60 6076D630 60C192BC 60C19428 60C197F0 60C1C0A0 60C1A434 60C1AD90 60C1BD38 60C1F2CC

I now have 20049 IDB's running because of unterminated/not properly closed virtual-access interfaces. Sheesh, there's no mention of any of this in the Cisco bug database for Cisco 7200's

According to Cisco's semi robotic Error Message Decoder

1. %INTERFACE_API-1-NOMORESWIDB: No more SWIDB can be allocated, maximum allowed [dec]
No more interfaces can be created because the maximum number of SWIDB allowed for this platform has been reached.

Recommended Action: Copy the error message exactly as it appears on the console or in the system log, contact your Cisco technical support representative, and provide the representative with the gathered information.
Related documents- No specific documents apply to this error message.

Funny thing, looks like this Error Message Decoder doubles as a Sales Agent for Cisco TAC.

Don't use c7200-is-mz.123-9c.bin IOS to avoid this kind of scalability error.

My new language

From tomorrow's training afterwards, I'll be learning a new language, the ShadeTree language to run my new toy.


protocols {
ospf {
rib-group ospf-multicast;
area 0.0.0.0 {
interface ge-u0/1.0;
interface ge-u0/2.0;
interface ge-u0/3.0 {
passive;
}
interface lo0.0 {
passive;
}
}
}
}

New learning curve for me, a new challenge!
