Configuration Guide 20. IPv6 Routing
20.3.2 Example of OSPFv3 Routing
This example demonstrates a typical scenario where an MSBR acts as a default gateway
for a LAN network, and connects to the WAN network using the OSPF6 protocol. This
example includes a single-area (area 0.0.0.5) OSPF6 network; however, in more complex
and large-scale networks, multi-area topology may be more adequate in terms of
scalability.
Figure 20-3: OSPF6 Routing
The following configuration demonstrates a basic OSPF6 configuration in which OSPF6 is
activated on the LAN interfaces (for advertisement) and on the WAN interfaces (for
adjacency forming). The router-ids are explicitly configured to the addresses of loopback
interfaces configured on the MSBR. Adjacency change logging is activated for debugging.
The OSPF6 timers are configured on the WAN interfaces of the MSBRs and should always
be matched on both ends to avoid adjacency flapping.

IPv6 address configuration is omitted, assume it is as described
in the topology above.
