Usage guidelines
Interworking enables a PW to connect ACs that have different link types, including ATM, FR, HDLC,
Ethernet, and PPP. In an IPv4 interworking scenario, a PE extracts IPv4 packets from frames received from
the AC and sends the packets to the peer PE through the PW. The peer PE uses the link protocol of the
connected AC to encapsulate the IPv4 packets and sends the packets through the AC. This method hides
the link types of ACs at the two ends.
IPv4 interworking discards non-IPv4 packets received from the AC.
When interworking is enabled, the PW type configuration does not take effect.
Examples
# Enable IPv4 interworking for the cross-connect ac2pw in the cross-connect group vpn1.
