Ссылка MPLS, не передавая
Вы посмотрели на и прочитали документацию, которую предоставляет Ubuntu? Они делают довольно хорошее задание, и они имеют много в наличии документации по установке. Я запустил бы с Общественной Страницы Установки Документации. Все, в чем Вы нуждаетесь, вероятно, тут же.
This was a dumb question, really. The routes are right. The answer is "troubleshoot your routers". Site A's router was replaced 3mo. ago because of failing memory. Site B's router is 12 years old and identical to the dead router. I eliminated site B's router with a new rv110 home/office router, set the same static routes, and the forwarding worked fine. The real problem was the fact that I could only troubleshoot one end at a time (without disrupting ongoing business), and I assumed that I was doing something wrong in the configuration.
Just sharing what I've learned over the course of this adventure...
For those newbs like me: your carrier will give you a gateway to plug your LAN into. They will want to give it a .1 address. If you have more than one innet connection and your gw is already .1, tell them to pound sand and set it to something outside your dhcp range. In my case, we got an inet connection for the WAN port and an MPLS circuit, which should be plugged into either the gateway's onboard switch or any other switch on the network (it's better on the gateway switch because you have a better chance of prioritizing VOIP traffic). Create a static route on each of your gateways that points to the other side of the VPN with the carrier's gateway set to the gw address. If you can't get communication, try replacing your routers, and check your firewalls. Once I had routing working, the dafault firewall was blocking traffic and the phones couldn't communicate, even though I could ping everywhere.
