Version Description
9.9(0.0) Introduced on the FN IOM.
9.2(0.0) Introduced on the MXL 10/40GbE Switch IO Module.
Usage Information Because this command is enabled by default, it does not appear in the running conguration. When you disable
unicast routing, the no ipv6 unicast-routing command is included in the running conguration. Whenever
unicast routing is disabled or re-enabled, the system generates a syslog message indicating the action.
Disabling unicast routing on a 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 conguration (under router bgp) is deleted
• IPv6 Multicast trac continues to ow unhindered
show ipv6 cam stack-unit
Displays the IPv6 CAM entries for the specied stack-unit.
Syntax
show ipv6 cam stack-unit unit-number port-set {0-0} [summary | index | ipv6
address]
Parameters
unit-number Enter the stack unit’s ID number. The range is from 0 to 5.
port-set Enter the keyword Port Set.
summary (OPTIONAL) Enter the keyword summary to display a table listing network prexes and
the total number prexes which can be entered into the IPv6 CAM.
index (OPTIONAL) Enter the index in the IPv6 CAM.
ipv6-address Enter the IPv6 address in the x:x:x:x::x/n format to display networks that have more
specic prexes. The range is from /0 to /128.
