Description
This article explains about difference in advertising the subnet/route in OSPFv3.
Solution
Overview.
- OSPF version 3 (OSPFv3) includes support for IPv6, configurable from the CLI only.
Generally, all IP addresses are in IPv6 format instead of IPv4.
However, OSPFv3 area numbers use the same 32-bit numbering system as OSPFv2, as described in RFC 2740.
Likewise, the router ID and area ID are in the same format as OSPFv2.
- For IPv6, the main difference in OSPFv3 is that rather than using a network statement to enable OSPFv3 on an interface.
Define OSPF6 (OSPF for IPv6) interfaces, which are bound to the interface and area.
This configuration needs to be done from the CLI, as follows (with sample interfaces and addresses):

CLI syntax (FGT1).
# config router ospf6Here, the Subnets associated with both the interfaces 'port1' and 'port4' will be advertised to the OSPFv3 neighbor (FGT2).
set router-id 1.1.1.1
# config area
edit 0.0.0.0
next
end
# config ospf6-interface
edit "1"
set interface "port1"
next
edit "2"
set interface "port4"
next
end
Interface Configuration: (FGT1).
# config system interfaceRoutes received Over OSPFv3 neighbor: (FGT2).
edit "port1"
# config ipv6
set ip6-address 9001::1/64
end
next
edit "port4"
# config ipv6
set ip6-address 2002::2/128
end
