trying to get L2 connectivity between PPPoE clients so that the intercom Panel can see the monitor (IPV6 only, cannot set an IPv4 address to it).
attached a drawing to show what we have. basically R1 is our core network, running a PPPoE server. R2, R3, R4 is customer site, running PPPoE client, then get Internet access.
what I want to do, is the blue part, where the Intercom panel needs to see the Monitors. Monitor is IPV6 only but if I just plug it into the same subnet in R1 it works fine, without me doing anything.
what I think the options are:
Keep the existing PPPoE setup, create VLAN interface on LAN side of R2, R3 and R4
run EoIP tunne from R2, R3, and R4 to R1
bridge VLAN at each router with EOIP tunnel, then bridge all EOIP tunnal at R1, all into one bridge so it is a big L2 netowrk.
this way VLAN is running over EOIP, which is over PPPoE
run VLAN between all routers, then
R2 will dial PPPoE on VLAN 10 (office traffic), say, and bridge all VLAN 20 at R2.
so that PPPoE is running over VLAN.
so are these possible ? good options?
any other alternatives are welcome!
