ipv6-address - The IPv6 address of the default next hop router to use for
destinations with no known next hop.
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 can only be successfully set when a network interface
that directly connects to the gateway has been configured on the router.
◆
An IPv6 default gateway must be defined if a destination is located in a
different IP segment and routing is disabled.
Example
The following example defines a default gateway for this device:
Console(config)#ipv6 default-gateway FE80::269:3EF9:FE19:6780%1
Console(config)#
show ipv6 nd raguard Displays the configuration setting for RA Guard
PE
show ipv6 neighbors Displays information in the IPv6 neighbor discovery cache PE
