Auditing a network to add Voice
by Kasper Adel 22 Nov '10

22 Nov '10

Hi, My customer would like to add VoIP over their network and they asked us for an audit. the result of the audit would be simply "you guys are ready for it" Breaking it down [high level] for me sounds like : (suggestions are more than welcomed) : 1) Looking at hardware computation finite resources (cpu, memory...etc) 2) Looking at available bandwidth 3) QoS policy 4) High Availability and Fast Convergence Any thing else? They asked us to measure the KPIs (jitter, delay...etc) of their existing traffic, is there a way to do that? Thanks, Kim

AS6453 (Tata/Teleglobe/Globe Internet?) <-> various US ISP Outage?

Anyone else seeing problems reaching AT&T/XO possibly others from AS6453 in Europe? From mclink.it (195.110.152.67), I see the following: [12-97-129-192:~] owen% traceroute 140.239.191.10 traceroute to 140.239.191.10 (140.239.191.10), 64 hops max, 52 byte packets 1 192.168.15.254 (192.168.15.254) 4.837 ms 4.359 ms 4.323 ms 2 192.168.250.1 (192.168.250.1) 4.593 ms 4.639 ms 4.561 ms 3 net152-001.mclink.it (195.110.152.1) 6.156 ms 6.119 ms 6.580 ms 4 213.21.129.56 (213.21.129.56) 32.659 ms 33.747 ms 32.600 ms 5 gw2-rm-te1.aknet.it (213.21.130.130) 32.604 ms 32.650 ms 33.107 ms 6 if-0-0-4.core1.rct-rome.as6453.net (195.219.163.33) 33.061 ms 33.313 ms 32.227 ms 7 if-7-0.core3.mlt-milan.as6453.net (195.219.158.49) 41.857 ms 41.912 ms 42.275 ms 8 * * * 9 * * * 10 * * * 11 * * * 12 * * * This is consistent for several other sites in net 12/8 and some others as well. The common denominator appears to be trying to get to XO or AT&T and dying at hop 7 as above. Owen

Cisco GRE/IPSec performance, 3845 ISR/3945 ISR G2
by Christopher J. Pilkington 19 Nov '10

19 Nov '10

We're running GRE/IPSec transport over a point-to-point DS3. We're also doing some QoS. The traffic mix is voice; our average packet size can be as low as 250 bytes at times. We are seeing incredibly high CPU when the traffic levels approach 30Mb/s and around 11kpps in each direction, at times over 95%. We've seen packet loss as well in the priority queue. We recently forklifted the routers on a point-to-point DS3 from 3845s to 3945s, thinking we'd see an improvement in performance. We saw no such improvement, and some on our team argue it's worse. I'm assuming here that the packet rate coupled with the QoS and GRE is just killing the router's CPU. That said, are there any optimizations that we could consider before ripping this thing out completely? Yes, cef is enabled. I'm considering changing from GRE/IPSec to VTI, but I suspect this will still have the same actual switching behavior through the router, and may not change anything. One other possibility was to run IPSec tunnel mode and just exclude EIGRP from the tunnel, but that may be risky (IPSec fails == black hole). Our fall back plan is swap out the DS3 with an ethernet and get a L2 ethernet encryptor, but that can't happen until 2011-01-01. Any suggestions, wisdom? Thanks, -cjp

That's what I'm hearing. Cogent refuses to peer with HE via IPv6. So cogent IPv6 Customers currently can not hit things at HE. And they can't do anything about it. Besides 6to4 tunneling and BGP peering with HE (or native, If they can).

Why is your company treating IPv6 turn ups as a sales matter?
by William Herrin 19 Nov '10

19 Nov '10

Hiya folks, Why are your respective companies treating IPv6 turn ups as a sales matter instead of a standard technical change request like IP addresses or BGP? Sprint and Qwest, I know you're guilty. How many of the rest of you are making IPv6 installation harder for your customers than it needs to be? Regards, Bill Herrin -- William D.
