Routed VPLS

Routed VPLS (R-VPLS) allows a VPLS instance to be associated with an IES IP interface.

NOTE: This is supported only in 7210 SAS-M in Access-Uplink mode and not in a Network

Within an R-VPLS service, traffic with a destination MAC matching that of the associated IP

interface is routed based on the IP forwarding table; all other traffic is forwarded based on the

VPLS forwarding table.

The R-VPLS service can be associated with an IPv4 interface and supports only static routing. It is

primarily designed for use of inband management of the node when operating the node in Access-

Uplink mode. It is useful for an inband management of ring for 7210 nodes using a single IPv4

NOTE: R-VPLS is primarily supported for inband management of the node and not for use to

provide customer service.

A standard IP interface within an existing IES service context may be bound to a service name. A

VPLS service only supports binding for a single IP interface.

While an IP interface may only be bound to a single VPLS service, the routing context containing

the IP interface (IES) may have other IP interfaces bound to other VPLS service contexts. In other

words, Routed VPLS allows the binding of IP interfaces in IES services to be bound to VPLS

When a service name is applied to any service context, the name and service ID association is

registered with the system. A service name cannot be assigned to more than one service ID.

Special consideration is given to a service name that is assigned to a VPLS service that has the

"configure>service>vpls>allow-ip-int-binding" command is enabled. If a name is applied to the

VPLS service while the flag is set, the system scans the existing IES services for an IP interface

that is bound to the specified service name. If an IP interface is found, the IP interface is attached

to the VPLS service associated with the name. Only one interface can be bound to the specified

If the allow-ip-int-binding command is not enabled on the VPLS service, the system does not

attempt to resolve the VPLS service name to an IP interface. As soon as the allow-ip-int-binding
