Explains how to configure nodes and interfaces for Layer 3 Outside (L3Out) connections. It covers defining border leaf switches, setting up routed interfaces, subinterfaces, and switched virtual interfaces (SVIs) to enable routing protocols and external connectivity. The chapter also details interface parameters such as IP addressing, VLAN encapsulation, and routing protocol settings to establish and manage external Layer 3 connections effectively. This configuration is essential for integrating the ACI fabric with external networks through L3Outs.
Modify L3Out interfaces using the GUI
Modifies an existing L3Out interface or adds an interface to a logical interface profile, including path, encapsulation, addressing, MTU, and DSCP settings.
Create an OSPF interface profile
Creates an OSPF interface profile for an L3Out interface and configures an interface policy, OSPFv2 authentication, or an OSPFv3 IPsec policy.
Create an OSPF timers policy
Creates an OSPF timers policy that defines interface metrics, administrative distance, ECMP, SPF scheduling, LSA processing, and LSA-limit behavior for a VRF.
OSPF max-metric
Describes how OSPF max-metric reduces a router's preference as a transit path by advertising locally generated LSAs with maximum metric values.
SVI External Encapsulation Scope
Explains how local and VRF scopes determine whether L3Out interfaces that use the same VLAN encapsulation have separate or shared bridge domains.
SVI External Encapsulation Scope
Explains how local and VRF scopes determine whether L3Out interfaces that use the same VLAN encapsulation have separate or shared bridge domains.
Encapsulation Scope Syntax
Maps the external SVI encapsulation scope options for an L3Out across the CLI, API, and GUI and describes the behavior of each option.
Guidelines for SVI External Encapsulation Scope
Lists the OSPF and BGP configuration requirements for deploying multiple L3Outs with SVI external encapsulation on the same node without routing conflicts.
Configure SVI external encapsulation scope using the GUI
Configures the external encapsulation scope for an SVI in an L3Out logical interface profile by using the Cisco APIC GUI.
Support for Multiple Encapsulations for L3Outs with SVIs
Explains how L3Out SVIs on different leaf switches can use different VLAN encapsulations while remaining in the same external bridge domain.
Group Multiple SVIs with Different Access Encapsulations
Explains how a bridge domain profile groups SVIs that use different access VLAN encapsulations into a single Layer 2 broadcast domain.
External bridge domain profile guidelines and limitations
Lists the operational constraints, compatibility requirements, and downgrade behavior for external bridge domain profiles that group SVIs with different access encapsulations.
Configure Multiple Encapsulations for L3Outs with SVIs Using the GUI
Configures an external bridge group profile and associates regular SVIs with the profile so that the SVIs can use different access encapsulations.
Configure Multiple Encapsulations for L3Outs with SVIs Using the CLI
Configures an external bridge profile and associates a regular SVI with the profile so that grouped SVIs can use different access encapsulations.
Configure Multiple Encapsulations for L3Outs with SVIs Using the REST API
Configures an external bridge profile and associates an SVI with the profile by sending XML payloads through the Cisco APIC REST API.
SVI Auto State
Explains how the SVI auto state setting determines whether an SVI remains operational when the interfaces in its associated VLANs are down.
SVI Auto State
Explains how the SVI auto state setting determines whether an SVI remains operational when the interfaces in its associated VLANs are down.
Guidelines and Limitations for SVI Auto State Behavior
Describes the configuration requirements for SVI auto state behavior. These guidelines ensure proper implementation of interface status management across individual virtual interfaces.
Configure SVI Auto State Using the GUI
Enables SVI auto state in an L3Out logical interface profile so that the SVI state depends on the operational state of its member interfaces.
Cisco Floating L3Outs
Explains how floating L3Outs provide external routing connectivity without requiring static logical interface paths, allowing connectivity to follow virtual machines between hosts.
