Routable Tunnel Endpoint Pool (RTEP) or External Tunnel Endpoint Pool (ETEP) is the required configuration for intersite L3out. The older version of MSO displays "Routable TEP Pools" while the newer version of MSO displays "External TEP Pools", but both are synonymous. https://www.cisco.com/c/en/us/support/docs/software/aci-data-center/217597-configure-intersite-l3out-with-aci-multi.html Intersite L3Out requires a external TEP address for the border leaf switches in each pod. If you already have an external TEP pool configured, for example for another feature such as Remote Leaf, the same pool can be used. The existing TEP pool will be inherited by the Multi-Site Orchestrator and shown in the GUI as part of the infra configuration. Otherwise, you can add a TEP pool in the GUI, as described in this section. https://www.cisco.com/c/en/us/td/docs/dcn/mso/3x/configuration/cisco-aci-multi-site-configuration-guide-311/aci-multi-site-use-case-l3out.html#id_119082

Stretched EPG Across Sites This Cisco ACI Multi-Site use case provides endpoint groups (EPGs) stretched across multiple sites. Stretched EPG is defined as an endpoint group that expands across multiple sites where the underlying networking, site local, and bridge domain can be distinct. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/aci/aci_multi-site/sw/1x/fundamentals/b_Cisco_ACI_Multi-Site_Fundamentals/b_ACI_Multi-Zone_Fundamentals_chapter_01.html https://www.cisco.com/c/en/us/support/docs/software/aci-data-center/217597-configure-intersite-l3out-with-aci-multi.html

Selected Answer: A
The support for Intersite L3Out mandates the deployment of a separate TEP pool (referred to as “external TEP pool” or “routable TEP pool”) for each site that is part of the Multi-Site domain https://www.cisco.com/c/en/us/solutions/collateral/data-center-virtualization/application-centric-infrastructure/white-paper-c11-739609.html#CiscoACIMultiSiteandL3Outconnectionsonborderleafnodes
