Unimus as NCM (Network Configuration Management) Tool
Hi Network Experts, Is anyone using Unimus as your main NCM tool in production? I am looking at an NCM tool that can scale upto 10,000 to 15,000 Network Devices. Do you recommend any other solution? The solution should atleast able to support network config backups, diffs, and basic network auditing features. https://unimus.net/ thanks Shahid

Saw 40-45% packet loss on both Lumen and ATT MPLS backbones
Wondering anyone else noticed it and the loss lasted approx 10 mins. I am wondering if one of our routers misbehaved or was there an actual SP loss?
Equinix type colo/Data Center in South Korea
I am wondering if anyone has experience hosting services in South Korea, who did you choose for colocation services and in what city? thanks, shahid

I dont think ISOC dashboard is updating any more. Google is no longer advertising but dashboard still shows green and TTLs were short on those records. \\ ; DiG 9.6.0-APPLE-P2 www.google.com in ;; global options: +cmd ;; Got answer: ;; -HEADER- opcode: QUERY, status: NOERROR, id: 15535 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;www.google.com.IN ;; ANSWER SECTION: www.google.com.588628INCNAMEwww.l.google.com. ;; Query time: 191 msec ;; SERVER: 2620:0:ccc::2#53(2620:0:ccc::2) ;; WHEN: Wed Jun 8 18:08:38 2011 ;; MSG SIZE rcvd: 52 On Wed, Jun 8, 2011 at 5:16 PM, George B. geor...@gmail.com wrote: On Wed, Jun 8, 2011 at 4:31 PM, Jorge Amodio jmamo...@gmail.com wrote: So if you are using a Netscaler with SLB-PT (IPv6 VIP balancing to IPv4 servers), the entire LB is subject to stop working until they get this fixed. And this is EXACTLY why we needed World IPv6 Day. Agreed, right on the money !! Traffic stats may not say a lot yet due to tunnels and lack of native IPv6 connectivity but finding this type of bugs is a major reason to do live tests, even if the test fails. Well, we are still attempting to recreate the problem. It isn't something as simple as someone coming in over a tunnel with a small MTU with a larger advertised MSS. There is some magic that must happen to actually put the unit in this state. We ran for 9 hours before and 9 hours after the hiccup without any problems. So it is going to take a while before we are ready to test this again live. The sooner I can recreate the problem, the better, though.
Re: Is anyone Using Talari Networks WAN Optimizer?
We are considering them but bit concern as they do forwarding plane optimization instead of control plane in case of Route Science. thanks, Shahid On Wed, Jan 19, 2011 at 2:50 PM, Holmes,David A dhol...@mwdh2o.com wrote: Talari management apparently has experience at the old Routescience BGP load-balancer startup, so this warrants a closer look. Has anyone used their products?
Re: Good MPLS/VPLS book?
Amazon has detailed TOC and couple of chapters online so you should get all the info. MPLS-TP gets a decent coverage in this book. thanks, Shahid On Sat, Dec 25, 2010 at 5:42 PM, Francois Menard franc...@menards.cawrote: Looks like a third edition is on the way slated for March 2011 http://www.amazon.com/MPLS-Enabled-Applications-Developments-Technologies-Communications/dp/0470665459/ref=ntt_at_ep_dpt_2 I would expect it to cover MPLS-TP and the struggling evolution of PBB-TE ... anybody has any idea if this is in ?

I understand the basics of what MPLS is and how you create a circuit from A to B but I'm afraid it still escapes me when trying to figure out how someone would, say, create a multicast capable VPN with 5 edge points. Any pointers to a good way to reduce my level of ignorance on this subject would be appreciated. Vendor literature doesn't bother me as long as the concepts are there.
