lifetime of 604,800 seconds (7 days).
Note that by default:
•
All prefixes are inserted in the routing table as connected prefixes.
•
All prefixes are advertised as on-link (for example, the L-bit is set in the
advertisement)
•
All prefixes are advertised as an auto-configuration prefix (for example, the
A-bit is set in the advertisement)

whether the prefix should be advertised.

Prefix table.
Use the no ipv6 nd prefix
from the Prefix table.
Use the no ipv6 nd prefix command without the
argument o remove all prefixes from the Prefix Table.
Note. The no ipv6 nd prefix command does not return the default values to the
original default values.
The switch supports the following advertisement algorithm:
•
Advertise all prefixes that are configured as addresses on the interface
using the parameters defined by the ipv6 nd prefix default command (or the
default value if the command has not been configured) except refixes that
are placed in the Prefix table (changed (configured) by the ipv6 nd prefix
command).
•
Advertise all prefixes configured by the ipv6 nd prefix command without
the no-advertise keyword.
