Routing

Hello Team,

We want to migrate our L2 collections from our Ericsson SSR LNS to a new MX240 LNS.

However, we have a specific configurations on the SSR

• A VLAN corresponds to a regional area, not to a client.
• Each VLAN is associated with a particular MAC address.

We have tried to apply this configuration on the MX240, but unfortunately, it appears that we can only assign a MAC address to an entire interface, not to a sub-interface.

We also tried putting the sub-interfaces in bridge mode, which allows us to configure the MAC address, but it is then impossible to have PPPoE on the sub-interface.

On the Ericsson side, the configuration looks like this

We have tried this configuration on the mx240, but ppp encap seems not working correctly.

Could any one assist me with this issue please ?
