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
show ipv6 cam stack-unit
Displays the IPv6 CAM entries for the specified stack-unit.
Syntax
show ipv6 cam [vrf vrf-name] stack-unit unit-number port-set {0-1} [summary |
index | ipv6 address]
Parameters
vrf vrf-name (Optional) Enter the keyword vrf followed by the name of the VRF to display IPv6 CAM
entries corresponding to that VRF.
NOTE: If you do not specify this option, IPv6 CAM entries corresponding to
the default VRF are displayed.
unit-number Enter the stack unit’s ID number.
