Outlines Layer 3 access configuration, emphasizing procedures for enabling multicast traffic with VRF using both GUI and CLI methods to support flexible and robust network management.
This chapter explains configuring Layer 3 wireless controller deployments on Cisco Catalyst 9800 series, covering L3 access setup, OSPF and PIM multicast integration, DHCP/NAT with VRF, and verification commands.
Layer 3 access
Explains Layer 3 access and how it enables routing and advanced networking features on Cisco Catalyst 9800 series wireless controllers.
OSPF protocols
Explains OSPF protocols, their key functions as link-state routing protocols, core authentication methods, notable features and enhancements in OSPF deployments.
PIM sparse mode
Explains how PIM sparse modes operate as multicast routing protocols, their reliance on explicit group membership, and the role of the Rendezvous Point (RP) in managing group traffic.
Network address translation (NAT)
Explains how network address translation (NAT) mechanisms map private network addresses to public addresses, supporting secure and scalable internet access.
