Display Message The show ipv6 route command displays the routing tables in the following format: Codes: C - connected, S - static, 6To4 - 6to4 Route , B - BGP Derived, D - Database Route 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, K - Kernel The columns for the routing table display the following information: Fields Definition Code The code for the routing protocol that created this routing entry. IPv6-Prefix/IPv6-PrefixLength The IPv6-Prefix and prefix-length of the destination IPv6 network corresponding to this route. Preference/Metric 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. Tag Displays the decimal value of the tag associated with a redistributed route, if it is not 0. Next-Hop The outgoing router IPv6 address to use when forwarding traffic to the next router (if any) in the path toward the destination Route-Timestamp Interface The last updated time for dynamic routes. The format of Route-Timestamp will be • Days:Hours:Minutes if days > = 1 • Hours:Minutes:Seconds if days < 1 The outgoing router interface to use when forwarding traffic to the next destnation. For reject routes, the next hop interface would be Null0 interface. T A flag appended to an IPv6 route to indicate that it is an ECMP route, but only one of its next hops has been installed in the forwarding table. The forwarding table may limit the number of ECMP routes or the number of ECMp groups. When an ECMP route cannot be installed beacause such a limit is reached, the route is installed with a single next hop. Such truncated routes are identified by a T after the interface name. 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. Reject routes are supported in both OSPFv2 and OSPFv3. NETGEAR M4500 Series Switches CLI Command Reference Manual 903

Display Message

The

show ipv6 route

command displays the routing tables in the following format:

Codes: C - connected, S

–

static, 6To4

–

6to4 Route

, B - BGP Derived, D - Database Route

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, K - Kernel

The columns for the routing table display the following information:

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. Reject routes are supported in both OSPFv2 and

OSPFv3.

Fields

Definition

Code

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

IPv6-Prefix/IPv6-Prefix-

Length

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

to this route.

Preference/Metric

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.

Tag

Displays the decimal value of the tag associated with a redistributed route, if it

is not 0.

Next-Hop

The outgoing router IPv6 address to use when forwarding traffic to the next

router (if any) in the path toward the destination

Route-Timestamp

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

•

Days:Hours:Minutes if days > = 1

•

Hours:Minutes:Seconds if days < 1

Interface

The outgoing router interface to use when forwarding traffic to the next

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

A flag appended to an IPv6 route to indicate that it is an ECMP route, but only

one of its next hops has been installed in the forwarding table. The forwarding

table may limit the number of ECMP routes or the number of ECMp groups.

When an ECMP route cannot be installed beacause such a limit is reached, the

route is installed with a single next hop. Such truncated routes are identified by

after the interface name.
