peer or peer group.
5. Configure the ASBR PE to
change the next hop to itself
when advertising routes to PEs
in the same AS.

use its address as the next hop
when advertising a route to its
IBGP peer or peer group.

export
By default, no routing policy is
applied to a peer or peer group.
Configuring the routing policy
After you configure and apply a routing policy on an ASBR PE, it does the following:
• Assigns MPLS labels to the routes received from the PEs in the same AS before advertising them to
the peer ASBR PE.
• Assigns new MPLS labels to the labeled IPv4 routes to be advertised to the PEs in the same AS.
Which IPv4 routes are to be assigned with MPLS labels depends on the routing policy. Only routes that
satisfy the criteria are assigned with labels. All other routes are still common IPv4 routes.
For information about routing policy configuration, see Layer 3—IP Routing Configuration Guide.
To configure a routing policy for inter-AS option C on an ASBR PE:

Configuring nested VPN
For a network with many VPNs, if you want to implement layered management of VPNs and to conceal
the deployment of internal VPNs, nested VPN is a good solution. By using nested VPN, you can
