IP Fabric for Media Topology
Cisco's IP fabric for media solution supports a spine-leaf topology that consists of one spine switch and up to
nine leaf switches.
The Cisco Nexus 9236C or 9272Q switch can serve as the spine switch. The Cisco Nexus 9236C, 9272Q,
and 92160YC-X switches can act as leaf switches. The topology supports any combination of these leaf
switches, including using just one type of leaf switch.

Media sources and receivers connect to the leaf switches, and receivers initiate IGMP join requests to the leaf
switches in order to receive the media traffic.
Failure Handling
Cisco's IP fabric for media solution supports deterministic failure handling. When a link fails, the following
actions occur:
•
When a link fails between a source leaf switch and the spine switch, the spine switch executes the NBM
algorithm and requests for flows on other links, provided sufficient bandwidth is available.
•
When a link fails between the spine switch and a receiver leaf switch, the leaf switch executes the NBM
algorithm and requests for flows on other links, provided sufficient bandwidth is available.
•
Flows that are not impacted are not moved to other links.
•
When a link comes up, only new flows are forwarded across it, and previous flows are not moved back
to the link.
