 Description   

EFFECT:

FIB entries are not programmed for static routes added in routers with intervpnlink

DESCRIPTION:

FIB entries are not programmed for static routes added in routers with intervpnlink.

Steps:
=========
Create AccessNetwork, Outernetwork
Create Accesssubnet, Outersubnet
Create accessrouter and add an interface from access network
Create outerrouter and add an interface from outer network
Create an intervpnlink with endpoints from access/outernetwork and vpn uuids
Added 2 static routes in the routers as below
