Basic OSPFv3 is limited to IPv6 unicast routing. The <rfc id="5838">
|
||||
extension defines support for more address families (IPv4, IPv6, both
|
||||
unicast and multicast). The extension is enabled by default, but can be
|
||||
disabled if necessary, as it restricts the range of available instance
|
||||
IDs. Default value is yes.

|

When multiple OSPF protocol instances are active on the same links, they
|
||||
should use different instance IDs to distinguish their packets. Although
|
||||
it could be done on per-interface basis, it is often preferred to set
|
||||
one instance ID to whole OSPF domain/topology (e.g., when multiple
|
||||
instances are used to represent separate logical topologies on the same
|
||||
physical network). This option specifies the default instance ID for all
|
||||
interfaces of the OSPF instance. Note that this option, if used, must
|
||||
precede interface definitions. Default value is 0.
