Re: MPLS over GRE MTU question

How is MPLS over GRE supposed to work anyways? MPLS relies on injecting labels between MAC and IP. That's why it is called Layer-2,5 sometimes. GRE-payload is IP only, so I don't see a possibility to transport MPLS labels to establish an LSP. However it will work with proprietary EoIP, which is some...

Re: EOIP TCP problem

As long as there is no packetloss TCP will scale up the bandwidth even on high latency links.

But every tiny bit of packetloss on high latency links will kill throughput.

Maybe pulling one VLAN trough the slower link and two VLANs through the faster link.
Then make a 3x bonding out of all three VLANs.
