Information
Since this command is enabled by default, it does not appear in the running configuration.
When unicast routing is disabled, 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 learnt 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
