Configuring a VPRN Service with CLI
Configuring a VPRN Interface
Interface names associate an IP address to the interface, and then associate the IP interface with a
VPRN interface
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
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).
