Local VPLS
3
The endpoints connected to the Local VPLS can be untagged, dual tagged, or single-tagged as
members of the same or different VLANs. Using this function of Local VPLS, a router can receive
packets with particular tags or no tag on one endpoint and forward them to the Local VPLSs other
endpoint, which may be untagged, dual-tagged, or single-tagged with a different VLAN tag. When so
configured, the tags within the packets are changed to reflect the configuration of the egress port
as they leave the router. This configuration performs the same function that the VLAN translation
feature performed in releases prior to 4.0.00.
Example Local VPLS configuration
In Figure 56 the Local VPLS named “Test1” contains Ethernet ports 1/1, 2/1, and 3/1. Port 1/1 is
a member of VLAN 100, port 2/1 is a member of VLAN 200, and port 3/1 is a member of VLAN
300. Because all of the ports belong to Local VPLS “Test1”, traffic tagged with any of the
configured tags (100, 200, or 300) can reach traffic within any of the three VLANs. For example,
traffic that ingresses on port 1/1 must have a tag with the value “100” and egresses on port 2/1
with a tag value of “200” or egress on port 3/1 with a tag value of “300”.

CoS behavior for Local VPLS
NOTE
This section assumes that the user understands how QoS works.
Table 75 describes the expected Class of Service (CoS) behavior for VPLS packets when Local
VPLS is in effect.
