Configuring a VPRN Interface SAP
VP RN Interf ace SAP
VP RN inte rface A SAP is a combination of a port and encapsulation parameters which identifies the service access
point on the interface and within the SR. Each SAP must be unique within a router. A SAP cannot
be defined if the interface loopback command is enabled.
When configuring VPRN interface SAP parameters, a default QoS policy is applied to each
ingress and egress SAP. Additional QoS policies and scheduler policies must be configured in the
config>qos context. Filter policies are configured in the config>filter context and must be
explicitly applied to a SAP. There are no default filter policies.
VPRN interface ATM SAP parameters can only be configured on ATM-type MDAs and ATM-
configured ports. The periodic-loopback command can only be enabled when the
config>system>atm>oam context is enabled. See the 7750 SR OS Basic System Configuration
Guide.
Refer to OSPF Configuration Commands on page 1158 for CLI commands and syntax.
The following example displays a VPRN interface SAP configuration:
