Re: [j-nsp] OSPF question

2017-09-21 Thread Andrey Khomyakov
Sure you can. Run something like quagga on the server for OSPF, configure your 1g links as /31s. The key is to attach your service to a loop back IP on their server and advertise that loop back using quagga to your router. I'd also make each of the 1g links a point to point ospf type.

"My opinion on QoS for networks with low bandwidth is to always implement it." Most definitely. Scheduled drops are always better than tail drops. As for microbursts, I can't say I'm very knowledgeable about what that is. I'm guessing that we are talking about extremely brief periods when egress

Sure, you could mitigate some of that with enforcing w/ever at the boundaries, but hopefully you are starting to see how a simple QoS policy design on a single node is blowing up into managing hundreds/thousands of ports and making sure you trust your VoIP telephone, but not the workstation behind

You could end up in a DoS situation where some rouge source send 1gbps worth of packets matching your priority class. That's just of top of my head. Also, depending on what you decide to match on (e.g IP, DSCP marks, ingress iface, etc) you'll constantly will have to tinker with the policy

My understanding was that if you don't have congestion, QoS is simply useless for a number of reasons: 1. You spend engineering hours writing/debugging policy that will never get used (we assuming no congestion) 2. QoS on egress will not go into effect (other than incrementing counters) because
