Hey Folks,
Looking for some help here.
I have an RB1000 with two WAN providers, each is providing me with VLANS to my branches.
One WAN provider is working perfectly with a routed network.
The second WAN provider uses ECI telecom (an Israeli manufacturer) for their Nationwide Fibre network.
I receive from the providers ECI switch in the entrance facility 3 VLANS (numbered 3000 3001 and 43). I have a /28 subnet for these subnets to use, and so I have combined the three VLANS together with a bridge and applied 172.220.21.1/28 to that bridge.
Now heres the weird stuff.
1: All the remote sites on VLAN 3000 work perfectly.
2: The remote sites using vlan 43 and 3001 cannot work at all, I see no mac addresses on those VLAN interfaces.
3: If I remove the vlan 43 and 3001 from the bridge and put some other subnet /30 there the vlan works fine, so the provider has mapped VLANS properly.
Can anyone give some tips as to why this design should not work?
Many thanks,
Alex
