flag is configured on the VPLS, the corresponding IP interface is adhered and become operational
up. There is no need to toggle the shutdown or no shutdown command.
If an IP interface is not currently bound to the service name used by the VPLS service, no action is
taken at the time of the service name assignment.

Service Binding Requirements

In the event that the defined service name is created on the system, the system checks to ensure
that the service type is VPLS. If the created service type is VPLS, the IP interface is eligible to
enter the operationally upstate.

Bound Service Name Assignment

In the event that a bound service name is assigned to a service within the system, the system first
checks to ensure the service type is VPLS. Secondly the system ensures that the service is not
already bound to another IP interface through the service name. If the service type is not VPLS or
theservice is already bound to another IP interface through the service ID, the service name
assignment fails.
A single VPLS instance cannot be bound to two separate IP interfaces.

Binding a Service Name to an IP Interface

An IP interface within an IES service context may be bound to a service name at anytime. Only
one interface can be bound to a service. When an IP interface is bound to a service name and the
IP interface is administratively up, the system scans for a VPLS service context using the name
and takes the following actions:
7210 SAS M Services Guide
If the name is not currently in use by a service, the IP interface is placed in an
operationally down: Non-existent service name or inappropriate service type state.
If the name is currently in use by a non-VPLS service or the wrong type of VPLS service,
the IP interface is placed in the operationally down: Non-existent service name or
inappropriate service type state.
If the name is currently in use by a VPLS service without the allow-ip-int-binding flag set,
the IP interface is placed in the operationally down: VPLS service allow-ip-intbinding
flag not set state. There is no need to toggle the shutdown or no shutdown command.
If the name is currently in use by a valid VPLS service and the allow-ip-int-binding flag is
set, the IP interface is eligible to be placed in the operationally up state depending on other
operational criteria being met.
