IPv6 Commands

ProSafe M4100 and M7100 Managed Switches

Note: If you use the connected keyword for <protocol>, the all option is not

available because there are no best or non-best connected routes.

The show ipv6 route command displays the routing tables in the following format:

Codes: C - connected, S - static

O - OSPF Intra, OI - OSPF Inter, OE1 - OSPF Ext 1, OE2 - OSPF Ext 2

ON1 - OSPF NSSA Ext Type 1, ON2 - OSPF NSSA Ext Type 2

The columns for the routing table display the following information:

Code

IPv6-Prefix/IPv6-

Prefix-Length

Preference/Metric

Tag

Next-Hop

Route-Timestamp

• Days:Hours:Minutes if days > = 1

• Hours:Minutes:Seconds if days < 1

Interface

To administratively control the traffic destined to a particular network and prevent it from

being forwarded through the router, you can configure a static reject route on the router. Such

traffic would be discarded and the ICMP destination unreachable message is sent back to the

source. This is typically used for preventing routing loops. The reject route added in the RTO

is of the type OSPF Inter-Area. Reject routes (routes of REJECT type installed by any

protocol) are not redistributed by OSPF/RIP. Reject routes are supported in both OSPFv2

and OSPFv3.

Format show ipv6 route [{<ipv6-address> [<protocol>] |

{{<ipv6-prefix/ipv6-prefix-length> | <slot/port>} [<protocol>] |

<protocol> | summary} [all] | all}]

Modes

• Privileged EXEC

• User EXEC

Route Codes

The key for the routing protocol codes that might appear in the routing table output.

Term Definition

The code for the routing protocol that created this routing entry.

The IPv6-Prefix and prefix-length of the destination IPv6 network corresponding to this

route.

The administrative distance (preference) and cost (metric) associated with this route. An

example of this output is [1/0], where 1 is the preference and 0 is the metric.

The decimal value of the tag associated with a redistributed route, if it is not 0.

The outgoing router IPv6 address to use when forwarding traffic to the next router (if any)

in the path toward the destination.

The last updated time for dynamic routes. The format of Route-Timestamp will be

The outgoing router interface to use when forwarding traffic to the next destination. For

reject routes, the next hop interface would be Null0 interface.
