Hello,
It’s possible to create trunk connection using BCP protocol ? I try to configure it but i cant add BCP interface (SSTP) to Bridge VLAN tagged field . I need send 3 VLANs to remote location but I don’t have public IP in branch office.
I didn’t try with BCP over SSTP (haven’t even noticed this was possible), but I’ve tried with BCP over L2TP and it didn’t work with vlan-filtering=yes on the bridge, I had to use EoIP for the purpose.
Yes 
, you can use any PPP protocol with MPPP to create BCP connection ( look at MUM presentations from USA / Cambodia / Manyar ) . Back to EoIP , i need to create a separate tunnel for each VLAN or maybe only one is enough ?
With EoIP, vlan-filtering=yes works as expected, so a single EoIP tunnel can be used the same way as a physical link, i.e. to carry at most one VLAN tagless and as many tagged VLANs as you need. As I wrote in the other post, with vlan-filtering=no even the BCP is suitable for transport of VLAN-tagged frames.
which one is better BCP or EOIP? i run layer 2 network
BCP with some PPP Multilink Protocol is better choice for me .I choose L3 reconstruction against L4 re/segmenting. Pros = bigger MTU, smaller CPU usage, no issues due to MSS for some services , one ppp tunnel for transport many EoIPs respectively VLANs.
