In the context of ACI Multi-Site, when is the information of an endpoint (MAC/IP) that belongs to site 1 advertised to site 2 using the EVPN control plane?

Question

Options

• AEndpoint information is not exchanged across sites unless COOP protocol is used.
• BEndpoint information is not exchanged across sites unless a policy is configured to allow
• CEndpoint information is exchanged across sites as soon as the endpoint is discovered in one site.
• DEndpoint information is exchanged across sites when the endpoints are discovered in both sites.

• B
  93% (39)
• C

Explanation

Endpoints EP1 and EP2 connect to separate Sites 1 and 2. A COOP notification is generated inside each fabric from the leaf nodes on which EP1 and EP2 are discovered and sent to the local spine nodes. The endpoint information is stored in the local COOP database. Spine nodes in site 1 know about locally connected endpoints, and the same is true for spine nodes in site 2. Note that at this point no information is exchanged across sites for EP1 and EP2 EPGs, because there is no policy in place yet indicating a need for those endpoints to communicate. An intersite policy is defined in Cisco Multi-Site Orchestrator and is then pushed and rendered in The creation of the intersite policy triggers Type-2 EVPN updates across sites to exchange EP1 and EP2 host route information.
