To specify the interval used for tracking IP addresses on endpoints, create an Endpoint Retention policy by sending a post with XML such as the following example:
<fvEpRetPol bounceAgeIntvl="630" bounceTrig="protocol"
holdIntvl="350" lcOwn="local" localEpAgeIntvl="900" moveFreq="256"
name="EndpointPol1" remoteEpAgeIntvl="350"/>When creating the subnet for the static route, it is configured under the EPG (fvSubnet object under fvAEPg), associated with the pervasive BD (fvBD), not the BD itself.
The subnet mask must be /32 (/128 for IPv6) pointing to one IP address or one endpoint. It is contained in the EPG associated with the pervasive BD.

An SR-MPLS infra L3Out will be scoped to a pod or a remote leaf switch site.
Border leaf switches or remote leaf switches in one SR-MPLS infra L3Out can connect to one or more provider edge (PE) routers in one or more routing domains.
A pod or remote leaf switch site can have one or more SR-MPLS infra L3Outs.
Each SR-MPLS infra L3Out should have a unique provider label and one provider label only. Each SR-MPLS infra L3Out is identified by the provider label.
You will configure the following pieces when configuring the SR-MPLS infra L3Out:
Nodes
Only leaf switches are allowed to be configured as nodes in the SR-MPLS infra L3Out (border leaf switches and remote leaf switches).
Each SR-MPLS infra L3Out can have border leaf switches from one pod or remote leaf switch from the same site.
Each border leaf switch or remote leaf switch can be configured in multiple SR-MPLS infra L3Outs if it connects to multiple SR-MPLS domains.
You will also configure the loopback interface underneath the node, and a node SID policy underneath the loopback interface.
Interfaces
Supported types of interfaces are:
Routed interface or sub-interface
Routed port channel or port channel sub-interface
For sub-interfaces, any VLAN tag is supported.
You will also configure the underlay BGP peer policy underneath the interfaces area in the SR-MPLS infra L3Out.
QoS rules
You can configure the MPLS ingress rule and MPLS egress rule through the MPLS QoS policy in the SR-MPLS infra L3Out.
If you do not create an MPLS QoS policy, any ingressing MPLS traffic is assigned the default QoS level.
You will also configure the underlay and overlay through the SR-MPLS infra L3Out:
Underlay: BGP peer IP (BGP LU peer) configuration as part of the interface configuration.
Overlay: MP-BGP EVPN remote IPv4 address (MP-BGP EVPN peer) configuration as part of the logical node profile configuration.
Review the SR-MPLS guidelines and limitations provided in Guidelines and Limitations for SR-MPLS, especially the guidelines and limitations provided in Guidelines and Limitations for the SR-MPLS Infra L3Out.
(Optional) If necessary, configure an MPLS custom QoS policy using the procedures provided in Creating SR-MPLS Custom QoS Policy Using REST API.

Post with information similar to the following: |
Using the procedures in this section, you will configure a SR-MPLS VRF L3Out, which will be used to forward traffic from the SR-MPLS infra L3Out that you configured in the previous set of procedures.
User tenant VRFs are mapped to the SR-MPLS infra L3Outs to advertise tenant bridge domain subnets to the DC-PE routers and import the MPLS VPN routes received from the DC-PE.
You must specify routing and security policies in the SR-MPLS VRF L3Out for each VRF. These policies point to one or more SR-MPLS infra L3Outs.
One SR-MPLS VRF L3Out is supported for each VRF.
You can configure multiple consumer labels in one SR-MPLS VRF L3Out, with each consumer label identifying one SR-MPLS infra L3Out. A consumer label identifies the entry and exit point for traffic to and from one SR-MPLS VRF L3Out, which is a particular MPLS domain for a particular pod or remote leaf switch.
Review the SR-MPLS guidelines and limitations provided in Guidelines and Limitations for SR-MPLS, especially the guidelines and limitations provided in Guidelines and Limitations for the SR-MPLS VRF L3Out.

Example: |
SR-MPLS Custom QoS policy defines the priority of the packets coming from an SR-MPLS network while they are inside the ACI fabric based on the incoming MPLS EXP values defined in the MPLS QoS ingress policy. It also marks the CoS and MPLS EXP values of the packets leaving the ACI fabric through an MPLS interface based on IPv4 DSCP values defined in MPLS QoS egress policy.
If no custom ingress policy is defined, the default QoS Level (Level3) is assigned to packets inside the fabric. If no custom egress policy is defined, the default EXP value of 0 will be marked on packets leaving the fabric.

Step 1 |
Create SR-MPLS QoS policy. In the following POST:
