2.3.5 Configure to Use IS-IS between a MCE and a PE

When configuring to use IS-IS between a MCE and a PE, you need to configure the
IS-IS processes to be bound to VPN instances and manually import the VPN routes in
the site maintained by the MCE device to the routing table of the PE.
In IS-IS, routes discovered by other routing protocols are external routes. While
importing routes of other protocols, you can specify the default cost value for the
imported routes as well. You can also apply filter policies for imported routes.
