VII. Configuring multi-role host attribute
After the configuration of the routing switch between PEs,, configure these items on PE
to achieve multi-role application with the site connected.
Step 1: Configure VPN-instance.
In multi-role application, a site is connected to a PE through physical port, but it can
access multiple VPNs. So you need to configure multiple VPN-instances on the PE and
bind the site port with the desired VPNs. For details about VPN-instance configuration,
see the section "Defining VPN-instance".
Step 2: Configure policy routing
If policy routing has been enabled and the route-policy conditions have been met, the
command in the following table can be used to specify the system to forward the
packets along the route found by looking up the configured vpn-name1, vpn-name2,
vpn-name3, vpn-name4, vpn-name5, and vpn-name6.
Perform the following configuration in route-policy view.

Step 3: Configure a private static route
Configure a static route to specify an interface in another VPN as egress interface, so
that the packets from PE to CE can be returned directly to the site.
Perform the following configurations in system view.
