IPv6 Interface
Interface Address Configuration and Utilities
ipv6 default-gateway
This command sets an IPv6 default gateway to use when the destination is located in a different
network segment. Use the no form to remove a previously configured default gateway.
Syntax
ipv6 default-gateway ipv6-address
no ipv6 address
ipv6-address - The IPv6 address of the default next hop router to use when the destination
is located in a different network segment.
Default Setting
No default gateway is defined
Command Mode
Global Configuration
Command Usage
• All IPv6 addresses must be according to RFC 2373 “IPv6 Addressing Architecture,” using 8
colon-separated 16-bit hexadecimal values. One double colon may be used in the address to
indicate the appropriate number of zeros required to fill the undefined fields.
• The same link-local address may be used by different interfaces/nodes in different zones (RFC
4007). Therefore, when specifying a link-local address, include zone-id information indicating
the VLAN identifier after the % delimiter. For example, FE80::7272%1 identifies VLAN 1 as the
interface.
• An IPv6 default gateway must be defined if the destination has been assigned an IPv6 address
and is located in a different IP segment. Otherwise, you can define a static route using the
ip
route command to ensure that traffic to the designated address or subnet passes through a
preferred gateway.
• An IPv6 default gateway can only be successfully set when a network interface that directly
connects to the gateway has been configured on the switch.
Example
The following example defines a default gateway for this device:
Console(config)#ipv6 default-gateway FE80::269:3EF9:FE19:6780
Console(config)#
ipv6 nd reachable-time Configures the amount of time that a remote IPv6 node is considered
reachable after some reachability confirmation event has occurred IC
clear ipv6 neighbors Deletes all dynamic entries in the IPv6 neighbor discovery cache PE
show ipv6 neighbors Displays information in the IPv6 neighbor discovery cache PE
