CLEC's in Ottawa area?
by chris 06 Sep '12

06 Sep '12

Hello, I have a client in the ottawa ontario canada area who is looking at DSL for a secondary connection. I am pretty unfamiliar with the state of telecom industry in Canada, I googled around and found this rather lengthy list of CLEC's. http://support.crtc.gc.ca/tlcmlsts/default.aspx?indx=33&lang=e Does anyone have any good experiences with any of these carriers that service the Ottawa they could share? Also would be an added plus if they supported MLPPP as the client mentioned they were concerned with the lower speeds of DSL, so we would love to do two circuits with MLPPP if possible thanks! chris

dot1q encapsulation overhead?
by up＠3.am 06 Sep '12

06 Sep '12

A while back we had a customer colocated vpn router (2911) come in and we put it on our main vlan for initial set up and testing. Once that was done, I created a separate VLAN for them and a dot1q subinterface on an older, somewhat overloaded 2811. I set up the IPSec Tunnel, a /30 for each end to have an IP and all the static routes needed to make this work and it did. However, a few days later they were complaining of slow speeds...I don't recall, but maybe something like 5mbs when they needed 20 or so. We had no policing on that port. After a lot of testing, we tried putting them back on the main, native vlan and it worked fine...they got the throughput they needed. So my question is: could the dot1q encapsulation be causing throughput issues on a 2811 that's already doing a lot? I regret that I don't recall what "sh proc cpu" output was, or if I even ran it at all. It was kind of hectic just to get it fixed at the time. Well, a few months later (last week), the chicken came home to roost when their IPSec tunnel started proxy ARP puking stuff to our side that temporarily took out parts of our internal LAN. I have requested a 2911 replacement for the 2811 because I have seen the 2811 cpu load max out a few times when passing lots of traffic. I am hoping it will allow us to go back to this VLAN setup again, but I've never heard whether dot1q adds any overhead.

So, in other words, it's ok to rant and stomp our feet about the end-to-end architecture and how critical it is to support in order to diss NAT, but we're required to ignore it when discussing SMTP? I'm not sure I'm following, there. Cheers, -- jra -- Jay R.

Level 3 BGP Advertisements
by Nick Olsen 05 Sep '12

05 Sep '12

Greetings all. In practice, We've always advertised our space all the way down to /24's but also the aggregate block (the /20 or the /21). Just so there was still reachability to our network in the event that someone made the foolish mistake of filtering lets say prefixes smaller /23... Anyways, I've always thought that was standard practice. And its never been a problem. Until we brought up peering with level 3.. I noticed that while the /24's made it out to the world. The larger counterparts (2 /21's and a /20) did not. So, I start sniffing around. Find that I do indeed see the prefixes in Level 3's looking glass but they aren't handing it off to peers. So, Naturally, I land on this being some kind of prefix filtering issue and open a ticket with Level 3. They tell me this is standard practice. And If I want to see the /20 or /21's make it out to the rest of the world, I need to stop sending the /24's. Does this sound normal? Is what I'm doing (Advertising the aggregate prefix) a good rule of thumb? Any other thoughts? Nick Olsen Network Operations (855) FLSPEED x106

Blocking MX query
by Ibrahim 05 Sep '12

05 Sep '12

Hi All, I've read old archive about blocking SMTP port (TCP port 25). In my current situation we are mobile operator and use NAT for our subscribers and we have few spammers, a bit difficult to track it because mostly our subscribers are prepaid services. If we block TCP port 25, there might be "good" subscribers will not be able to send email. We are thinking to block MX queries on our DNS server, so only spammer that use their own SMTP server will got affected. All DNS queries from our subscribers already redirected to our DNS cache servers. But seem Bind don't have feature to block MX query. Any best practice to block MX query? Regards Ibrahim
