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, FTOS
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
