IP Addressing 225
• No Onlink —Configures the specified prefix as not onlink. A no
onlink prefix is inserted into the routing table as a connected
prefix but advertised with a L-bit clear.
•
Offlink —Configures the specified prefix as offlink. The prefix will
be advertised with the L-bit clear. The prefix will not be inserted
into the routing table as a connected prefix. If the prefix is already
present in the routing table as a connected prefix (for example,
because the prefix was also configured by adding an IPv6 address),
it will be removed.
