Figure 12-65 PW-HE Interface
The PW-HE interface is treated like any existing L3 interfa ce and operates on on e of the follo wing nodes:
• Bridged interworking (VC type 5 or 4) node—PW will carry cust om er E th erne t fr am es w it h I P
payload. The S-PE device must perform ARP resolution for customer IP add resses l ear nt over
PW-HE, which acts as a broadcast interface.
• IP interworking node (VC type 11)—The PW-HE acts as a point-to-point interface. Hence, there will
be two types of PW-HE interface-PW-Ether and PW-IW. These PW’s can terminate into a VRF or
the IP global table on SP-E.
