You can subnet ipv6 with your eyeballs, just add or subtract 4 from the prefix length for every character you move to the left or right. 1234:1234:1234:1234::/64 1234:1234:1234:123X::/60 1234:1234:1234:12XX::/56 1234:1234:1234:1XXX::/52 1234:1234:1234::/48 etc -Original Message- From: ci

[c-nsp] Best bang for the buck in L2TP devices

So I'm running unencrypted L2TP back to my colo and currently have about 300 clients terminated to a 3825. Anyone have a good feeling for what the best bang for the buck would be to scale that up to 5000? I am looking at the ASA 5540s, but even Cisco pre-sales doesn't seem to be able to te

None. There is no common carrier between the two. The US has plenty to choose from. The Middle East has very few, all buying from one or two top tier in-region carriers. It is also likely that you will have to use a VPN between the sites, as any type of SIP/RTP/H.323 is likely to be bloc

I'm in the unfortunate position of having to support a bunch (100 or so now, 300 or so very soon) PPTP connections. Right now I'm using a 3825, and based on CPU performance it looks like I'll be lucky to get 200 on this thing with my typical end use usage patterns. Cisco seems to be prett

Re: [c-nsp] Extended demarc

If you're asking about T1s, we've extended a demarc 23 stories over Category 0 building pair from the 70s or 80s and the circuit has run flawlessly.

Multihoming is not always about redundancy, and the most likely point of failure is not always your own router. It is often something much more expensive, like your power. On May 13, 2009, at 4:06 PM, Robert Maier wrote: but if you are using Multihoming, only one router is single point of

Is there anyway to use a loopback interface as a management interface on a 2960? The option to create the loopback is there, but no management is available when I try to telnet. I've never used a loopback on a pure layer 2 device before, just curious to see if it was possible. Thanks ___
