VPRN RIP CLI Syntax
Use the CLI syntax to configure VPRN RIP parameters (RIP Configuration Commands on page 
945).
The following displays the command usage to configure VPRN RIP parameters:
Example: config>service>vprn# rip 
config>service>vprn>rip# export vprnRipExpPolCust1
config>service>vprn>rip# group "cel"
config>service>vprn>rip>group# neighbor "to-cel"
config>service>vprn>rip>group>neighbor# exit
config>service>vprn>rip>group# exit
config>service>vprn>rip#
The following example displays the VPRN RIP configuration:
