Configuring a VPRN Service with CLI
Page 916 7750 SR OS Services Guide
Configuring a VPRN Interface
VPRN interface Interface names associate an IP address to the interface, and then associate the IP interface with a 
physical port. The logical interface can associate attributes like an IP address, port, Link 
Aggregation Group (LAG) or the system. 
There are no default interfaces. 
Note that you can configure a VPRN interface as a loopback interface by issuing the 
loopback 
command instead of the 
sap sap-id command. The loopback flag cannot be set on an interface 
where a SAP is already defined and a SAP cannot be defined on a loopback interface.
When using mtrace/mstat in a Layer 3 VPN context then the configuration for the VPRN should 
have a loopback address configured which has the same address as the core instance's system 
address (BGP next-hop).
Refer to OSPF Configuration Commands on page 943 for CLI commands and syntax.
The following displays the command usage to configure VPRN interface parameters:
Example: config>service# vprn 1 
config>service>vprn# interface "to-ce1" create
config>service>vprn>if$ address 10.1.1.1/24
config>service>vprn>if# no shutdown
The following example displays the VPRN interface configuration:
