13.
Disable route target based
filtering of VPNv4 routes.
undo policy vpn-target
By default, the PE filters received
VPNv4 routes by route targets.
The routes surviving the filtering
are added to the routing table, and
the others are discarded.
Configuring inter-AS option C
To configure inter-AS option C, configure PEs and ASBRs.
• PE configuration:
 Configure basic MPLS L3VPN, and specify the PE in another AS as an MP-EBGP peer. The
route targets for the VPN instances on the PEs in different ASs must match for the same
VPN.
 Execute the peer ebgp-max-hop command to enable the local router to establish an EBGP
session to an indirectly-connected peer because the PEs are not directly connected.
 Specify the ASBR in the same AS as an IBGP peer, and enable BGP to exchange labeled
IPv4 unicast routes with the ASBR.
• ASBR configuration:
 Configure a routing protocol, and enable MPLS and LDP on the interface connecting to an
internal router of the AS.
 Specify the PE in the same AS as an IBGP peer, and the ASBR in a different AS as an
EBGP peer.
 Enable BGP to exchange labeled IPv4 unicast routes with the PE in the same AS and the
ASBR in different AS.
 Enable MPLS on the interface connected to the remote ASBR. There is no need to
configure a label distribution protocol, for example, MPLS LDP.
 Configure a routing policy to determine which IPv4 unicast routes are advertised to the
IBGP or EBGP peer with MPLS labels.
In addition, configure BGP to advertise routes destined for a PE on PEs or ASBRs. For more
information, see Layer 3—IP Routing Configuration Guide.
Configuring a PE
For basic MPLS L3VPN configurations on a PE, see "Configuring basic MPLS L3VPN." The
following table describes inter-AS option C specific configurations.
