PEI brings the SAP in VPWS 4 operationally down.

PE3 sets the P flag in its advertised A-D per EVI route to I.

PE2 receives a single A-D per EVI route. The route is originated from PE3.

PE2 receives two A-D per ES routes: one from PEI and another from PE3.

Allows Tx unicast, blocks Rx unicast, allows Tx BUM, blocks Rx BUM

PEI populates this information into the local VPLS FDB.

Neighbors 10.10.10.2 and 10.10.10.3 have proxy-ARP enabled for the VPLS.

Neighbors 10.10.10.2 and 10.10.10.3 have a service that uses a network identifier of 10.

PEI uses VXLAN tunnels to reach neighbors 10.10.10.2 and 10.10.10.3.

PEI does not flood the packet because PEI is acting as non-designated forwarder (non-DF) for VPLS 10.

PEI sends the packet to PE2 but not to PE3 because PE3 is connected to the originating ES.

PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE2.

PEI sends the packet to PE2 and to PE3. An ESI label is included only in the packet sent to PE3.

The flooding list maintained by PEI for VPLS 20 contains three entries: PE2, PE3, and PE4.

PE3 advertises an IMET route to PEI when its VPLS 20's mesh-SDP becomes operationally UP.

PE3 signals a service label to PE4 when its VPLS 20 is enabled and is bound to an operational SDP.

PEI advertises a MAC route for MAC-OI when its VPLS 2(Ys SAP becomes operationally UP.

Ethernet segment (ES) routes indicate the redundancy mode of the Ethernet segment.

ES routes provide the ESI label required to support the split-horizon mechanism.

Auto-discovery (A-D) routes are imported by all PES participating in the EVPN service.

A-D per Ethernet segment routes indicate the desired designated forwarder election algorithm.

EVPN routes are advertised with a service label associated with the SBD VPLS.

IP-Prefix routes exchanged between PES include a non-zero gateway IP address as an overlay index.

EVPN MAC/IP routes are used to advertise the MAC and IP addresses of local hosts.

EVPN MAC/IP routes are used to advertise the MAC and IP addresses of SBD IRB interfaces.
