Usage Information
Because this command is enabled by default, it does not appear in the running configuration. When you disable unicast routing, the no ipv6 unicast-routing command is included in the running configuration. Whenever unicast routing is disabled or re-enabled, DellEMC Networking OS generates a syslog message indicating the action.
Disabling unicast routing on an E-Series chassis causes the following behavior:
  • static and protocol learned routes are removed from RTM and from the CAM; packet forwarding to these routes is terminated
  • connected routes and resolved neighbors remain in the CAM and new IPv6 neighbors are still discoverable
  • additional protocol adjacencies (OSPFv3 and BGP4) are brought down and no new adjacencies are formed
  • the IPv6 address family configuration (under router bgp) is deleted
  • IPv6 Multicast traffic continues to flow unhindered
