Overview
Use this command to allow the processing of the prefix information included in a
received RA (Router Advertisement) on an IPv6 enabled interface.
Use the
no
variant of this command to disable an IPv6 interface from using the
prefix information within a received RA.
Syntax
ipv6 nd accept-ra-pinfo
no ipv6 nd accept-ra-pinfo
Default
The command
ipv6 nd accept-ra-pinfo
is enabled by default on any IPv6
interface.
Mode
Interface
Usage
By default, when IPv6 is enabled on an interface, SLAAC is also enabled. SLAAC
addressing along with the EUI-64 process, uses the prefix information included in
a received RA to generate an automatic link-local address on the IPv6 interface.
Note, an AlliedWare Plus device will, by default, add a prefix for the connected
interface IPv6 address(es) to the RA it transmits. However, this behavior can be
changed by using the command
no ipv6 nd prefix auto-advertise
, so there is no
guarantee that an RA will contain a prefix.
Example
To enable IPv6 on vlan1 without installing a SLAAC address on the interface, use
the following commands:
awplus#
configure terminal
awplus(config)#
interface vlan1
awplus(config-if)#
ipv6 enable
awplus(config-if)#
no ipv6 nd accept-ra-pinfo
