I realized that one Layer 3 switch does not really support VLAN, so I need another solution to create a virtual LAN.
According to the manual, these limitations will be removed in future firmware versions. The latest firmware is two years old, so no, they wouldn't fix it.
However, I can change the system mode to Layer 2 and use VLAN. I prefer not to do that, because it may be bottlenecks if I use a router to deal with the traffic.Note: When operating the switch in multilayer mode, all ports should be defined as untagged, and no VLANs can overlap. You should also assign the same default PVID to the ports at both ends of a link if the VLAN must cross the switches. (See “VLAN Tagging” configuration.) These limitations will be removed for future firmware versions.
Right now I'm using EoIP to bridge two networks. That was very easy to configure, and it's working quite well. There is only one problem, the throughput is not what I expected. It seems that EoIP tunnels requires a lot of CPU power, so I either need to replace the hardware or try something else.
What I need is a simple point-to-point Layer 2 bridge (Ethernet over MPLS).
I read that MTU issues can arise if the MPLS backbone cannot support MTUs larger than 1530. Do I need some special hardware (NICs) where I can set L2 MTU to mitigate this issue?
Thanks in advance.
