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, 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 configuration (under router bgp) is deleted
• IPv6 Multicast traffic continues to flow unhindered
