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 from which the ping is sent.
◆ An IPv6 default gateway must be defined if the destination has been
assigned an IPv6 address and is located in a different IP segment.
◆ 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.
