Re: Border routers

Thank you guys, This will be useful, but I still have some questions: Where can I see comparations between the routers? Also, where can I find datasheets containing FIB, RIB and BGP routes limits for cisco and Juniper? It is quite dificult!

Probes from root servers
by Pederson, Krishna 17 Jul '09

17 Jul '09

One of our IP addresses is being probed by up to 8 of the 13 root dns servers every 15 seconds. I'm looking for input on how to contact the admins for the servers or perhaps a way to figure out if perhaps someone is spoofing the affected customer IP address, causing the root servers to send the following: sh mls netflow ip destination 74.1.32.205 /32 module 2 Displaying Netflow entries in module 2 DstIP SrcIP Prot:SrcPort:DstPort Src i/f :AdjPtr ----------------------------------------------------------------------------- Pkts Bytes Age LastSeen Attributes --------------------------------------------------- 74.1.32.205 193.0.14.129 udp :dns :1039 Fa2/11 :0x0 0 0 1 22:49:03 L3 - Dynamic 74.1.32.205 202.12.27.33 udp :dns :1039 Fa2/11 :0x0 0 0 2 22:49:03 L3 - Dynamic 74.1.32.205 192.36.148.17 udp :dns :1039 Fa2/11 :0x0 0 0 2 22:49:03 L3 - Dynamic Is it practical to attempt to work the issue with the root server admins or is it quite likely this is spoofing and there's no hope to track this down? Thanks, Kris

Using CE Router for Internet and VPN services
by Akhmedd Aly 17 Jul '09

17 Jul '09

Hi, can someone explain me why service providers (Internet and/or L3 VPN services) obligate customers to use CE routers. Why they cannot configure more than /30 (in some cases /31) subnet mask on PE interface side for me? In that case I can use cheap L2 switch and use default gateway on all my PCs in the LAN, pointing to SP PE. Please describe all benefits and detriments of using more than /30 subnet on SP PE. Some good links will be very useful for me. TIA! -- AA

Border routers
by Livio Zanol Puppim 17 Jul '09

17 Jul '09

Hello guys, I need to buy 2 border routers to handle 2 155Mbps links using BGP full route with each ISP. What may I analyse at the routers hardware? I'm asking for: 1Giga Byte of RAM expansible to 1,5GB 1.000.000 FIB capacity in hardware (since 512K won't be enought soon) 1.000.000 RIB capacity. What do you recommend to ask for? Are these specifications ok? Do I need more RAM or less FIB? Is there any site I can use to see specifications for border routers? Anyone knows of any PoC involving routers? -- []'s Lívio Zanol Puppim

The actual value, from a security standpoint, of using a proxy domain registrar?
by Mike Lyon 16 Jul '09

16 Jul '09

Howdy, I am curious what others in the industry think on this topic. When one registers a domain they can put in their real information or they can use a proxy, like Go-Daddy's Domains By Proxy. Now, personally, I would prefer just to get a PO Box and put that address on my domain info instead of doing a proxy. I could also put down a phone number in the registration that just goes to my general business phone line which is just a DVR. So the question I have is this: What actual security are these proxy companies providing to the end-user? My company website has my real address, my real phone number, exec bio's and pictures of them yet upper management (and our marketing company) think using a proxy is a good thing. What's the difference between using a proxy vs using a PO Box except that a PO Box is cheaper? I'd just like to get thoughts from others to see what the general feeling is on this topic. Cheers, Mike

Shortest path to the world
by Sean Donelan 16 Jul '09

16 Jul '09

The typical network architecture problem, what are the best (shortest latency, greatest bandwidth, etc) locations to connect to the every nation in the world? As you increase the number of locations, how do the choices change? If you only had small (2 3 5 7 11) number of locations, where would they be? And what data do you have to prove the choices are best?
