This can be changed to point-to-point (PtP) / +point-to-multipoint (PtMP) mode by configuration. The actual physical +interface characteristics do not matter for this setting, all interfaces can +be configured for all modes. However, routers must be configured for the same +mode to form adjacencies. + +The main advantages of PtP/PtMP mode are: + +- no DR/BDR election +- adjacencies can be suppressed in a pairwise manner for any two routers, e.g. + to represent the underlying topology if it isn't a true full mesh +- distinct costs can be set for each pair of routers and direction + +The main downside is less efficient flooding on networks with a large number +of OSPFv3 routers. + +.. warning:: + + All options in this section should be considered "advanced" configuration + options. Inconsistent or nonsensical combinations can easily result in a + non-functional setup. + +.. clicmd:: ipv6 ospf6 p2p-p2mp disable-multicast-hello + + Disables sending normal multicast hellos when in PtP/PtMP mode. Some + vendors do this automatically for PtMP mode while others have a separate + ``no-broadcast`` option matching this. + + If this setting is used, you must issue + :clicmd:`ipv6 ospf6 neighbor X:X::X:X poll-interval (1-65535)` for each + neighbor to send unicast hello packets. + +.. clicmd:: ipv6 ospf6 p2p-p2mp config-neighbors-only + + Only form adjacencies with neighbors that are explicitly configured with + the :clicmd:`ipv6 ospf6 neighbor X:X::X:X` command.

Regardless of this setting, the router's own + address, as a /128 host route with the "LA" (Local Address) bit set, will + always be advertised. + + The default is to include connected prefixes for PtP mode and exclude them + for PtMP mode. Since these prefixes will cover other router's addresses, + these addresses can become unreachable if the link is partitioned if the + other router does not advertise the address as a /128. However, conversely, + if all routers have this flag set, the overall prefix will not be advertised + anywhere.
