Configuring external routed network connectivity involves the following steps:
Create a VRF under Tenant.
Configure L3 networking configuration for the VRF on the border leaf switches, which are connected to the external routed network. This configuration includes interfaces, routing protocols (BGP, OSPF, EIGRP), protocol parameters, route-maps.
Configure policies by creating external-L3 EPGs under tenant and deploy these EPGs on the border leaf switches. External routed subnets on a VRF which share the same policy within the ACI fabric form one "External L3 EPG" or one "prefix EPG".
Configuration is realized in two modes:
Tenant mode: VRF creation and external-L3 EPG configuration
Leaf mode: L3 networking configuration and external-L3 EPG deployment
The following steps are for creating an OSPF external routed network for a tenant. To create an OSPF external routed network for a tenant, you must choose a tenant and then create a VRF for the tenant.
Note |
The examples in this section show how to provide external routed connectivity to the "web" epg in the "OnlineStore" application for tenant "exampleCorp". |

||
|
Step 2 |
Configure the tenant VRF and enable policy enforcement on the VRF. Example: |

||
|
Step 4 |
Configure the VRF on a leaf. Example: |
||
|
Step 5 |
Configure the OSPF area and add the route map. Example: |
||
|
Step 6 |
Assign the VRF to the interface (sub-interface in this example) and enable the OSPF area. Example:
|
||
|
Step 7 |
Configure the external-L3 EPG policy. This includes the subnet to match for identifying the external subnet and consuming the contract to connect with the epg "web". Example: |
||
|
Step 8 |

This section describes how to configure QoS directly on an L3Out. This is the preferred way of configuring L3Out QoS starting with Cisco APIC Release 4.0(1).
You can configure QoS for L3Out on one of the following objects:
Switch Virtual Interface (SVI)
Sub Interface
Routed Outside
|
Step 1 |
Configure QoS priorities for a L3Out SVI. Example: |
|
Step 2 |
Configure QoS priorities for a sub-interface. Example: |
|
Step 3 |
Configure QoS priorities for a routed outside. Example: |
This section describes how to configure QoS for L3Outs using Contracts.
Note |
Starting with Release 4.0(1), we recommend using custom QoS policies for L3Out QoS as described in Configuring QoS Directly on L3Out Using CLI instead. |
|
Step 1 |
Configure the VRF for egress mode and enable policy enforcement to support QoS priority enforcement on the L3Out. |
||
|
Step 2 |
Configure QoS. access-list), include the match dscp command with target DSCP level.
VRF enforcement must be ingress, for QoS or custom QoS on L3out interface, VRF enforcement need be egress, only when the QOS classification is going to be done in the contract for traffic between EPG and L3out or L3out to L3out.

vrf context tenant infra vrf overlay-1
router-id 10.10.3.3
exit
interface ethernet 1/33
vlan-domain member golf_dom
