My setup:
CRS-125 ← ether → CCR-1036 ← sfp → CCR-1036 ← ether → CRS-125
On the CCR routers, I have bridged the ether and sfp interface with VLANs on the bridge.
I have no bridge filters set.
When I ping with packet size 1500, packets arrive and are replied to, so no issues with IP config.
When I ping with packet size 1501, the packet is correctly split up into 2 packets (1514 + 60), correctly forwarded on CCR1 to the sfp, and received on sfp by CCR2, but neither packet is being forwarded (on bridge) to the ethernet interface. Even more strangely, this happens in both directions.
What could be the reason for a bridge to discard packets?
