4.1.5 PWE3 MPLS Layer 2 VPN

Pseudo-Wire Emulation Edge-to-Edge (PWE3) is an extension of Martini mode.

The PWE3 sets up a PW on the control plane by using LDP. On the basis of the Martini mode,
PWE3 adds a notification mechanism and reduces the interaction of control packets when the
attachment circuit (AC) or the tunnel flaps. The PWE3 can also use Layer 2 TP version 3 as the
signaling. The Reservation Protocol (RSVP) can be used as a signaling protocol to set up a PW

with bandwidth guarantee, that is, RSVP-Traffic Engineering (RSVP-TE) PW. PWE3 mode is

compatible with Martini mode.

Figure 4-4 shows the PWE3 signaling process.
