Hi All,

I have a CCR1036 configured to handle S-tag/c-tags from a upstream provider across via a layer-2 switch. Please see diagram attached. If there is anything that needs clarification, please ask.

Here is an extract of the config file:
/interface bridge
add name=Br1 vlan-filtering=yes
add name=loopback0
/interface ethernet

set [ find default-name=sfp-sfpplus1 ] l2mtu=9216 mtu=9216
set [ find default-name=sfp-sfpplus2 ] l2mtu=9216 mtu=9216
/interface bonding
add lacp-rate=1sec mode=802.3ad mtu=9216 name=AggregatePort1 slaves=sfp-sfpplus1,sfp-sfpplus2
/interface vlan
add interface=AggregatePort1 name=Site2 vlan-id=20
add interface=AggregatePort1 name=Site1 vlan-id=10
add interface=Site1 name=S1VL10 vlan-id=10
add interface=Site2 name=S2VL10 vlan-id=10
/interface bridge port
add disabled=yes interface=AggregatePort7 (not sure why this line is here)
add bridge=Br1 interface=Site2 pvid=20
add bridge=Br1 interface=Site1 pvid=10
/ip address
add address=10.10.20.1/30 interface=S2VL10 network=10.10.20.0
add address=10.10.10.1/30 interface=S1VL10 network=10.10.10.0

Have been able to get some basic connectivity working using the nested vlan interfaces.

I have a few questions about automation and scalability:

1) Is there is a better solution for growth of network sites? Say 100+ for example
2) I would like to use DHCP on the Bridge interface to reduce the amount of overhead when bringing on new sites. Does this need to be done per nested vlan interface?

Thanks in advance!
