L2VPN Interworking Modes



L2VPN Interworking works in either Ethernet ("bridged") mode or IP ("routed") mode. You specify the mode by issuing the interworking {ethernet | ip} command in pseudowire-class configuration mode.



The interworking command causes the attachment circuits to be terminated locally. The two keywords perform the following functions:



•The ethernet keyword
 causes Ethernet frames to be extracted from the attachment circuit and 
sent over the pseudowire. Ethernet end-to-end transmission is assumed. 
Attachment circuit frames that are not Ethernet are dropped. In the case
 of VLAN, the VLAN tag is removed, leaving an untagged Ethernet frame.



•The ip keyword
 causes IP packets to be extracted from the attachment circuit and sent 
over the pseudowire. Attachment circuit frames that do not contain IPv4 
packets are dropped.
