I have a problem I hope can be figured out here. I need to transport proprietary Ethernet frames across an IP network while still routing IP packets on the same interfaces. It looks like IRB will do the trick but I am unclear as to how to get the bridged frames across the network to the other router.
Here's the scenario - There are two workstations used to control satellite bandwidth. They are geographically diverse but connected via private IP network. The two workstations use a proprietary Ethernet frame for some of the inter-communication between them while the same interface is used for managing the workstations via IP.
I've configured IRB on both routers with the âbridge irbâ command, configured the bridge group on the interface facing the workstations and created BVI interfaces for the bridge groups. I set the bridge protocol to IEEE and configured the bridge group to âroute ipâ. So far everything works fine, the workstations can see each other through IP, but I don't see the proprietary frames. How is it that the bridged frames get across the IP network?
I have included some documentation to help make this clear.
Would I be correct in assuming that the special Ethernet frames have an Ether type code of something other than IP? That would mean that the non-IP (special) frames are being bridged. So what you really need is some method of transporting the bridged frames over the IP network?
I would suggest that DLSw+ was designed to take non-routed/bridged traffic and encapsulate it in IP to transport over IP networks, and decapsulate it at the destination and bridge it on to its destination. And if you use DLSw+ then I believe that you do not need IRB on those routers.
I only get one interface in the routers to connect to the workstations. If I use L2TPv3 how can I be sure that IP connectivity still remains after I configure the PW. Won't L2TPv3 tunnel all frames across the PW?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
