Usage Information Because this command is enabled by default, it does not appear in the running conguration. When you
disable unicast routing, the no ipv6 unicast-routing command is included in the running
conguration. Whenever unicast routing is disabled or re-enabled, Dell 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 conguration (under router bgp) is deleted
• IPv6 Multicast trac continues to ow unhindered
