What is the primary function of VLAN interworking in Layer 2 VPNs?

To bridge Ethernet frames transparently

To route IP packets between VPNs

To map VLAN tags between different Layer 2 VPN encapsulations

How does LDP autodiscovery for VPLS establish sessions between PE routers?

By using BGP to exchange labels

By using RSVP-TE to establish sessions

By using targeted LDP sessions between PE routers

By using OSPF to discover PE routers

When configuring interworking between different Layer 2 VPN types, what must be ensured for proper data forwarding?

The customer edge devices are configured with static routes

All PE routers use the same vendor

Addressing translation and encapsulation mapping are correctly configured

In Ethernet interworking, what happens to the Ethernet frame when it is forwarded between different Layer 2 VPN types?

It is preserved and forwarded transparently

It is encrypted before forwarding

It is stripped of its header and re-encapsulated

It is converted to an IP packet
