OSPFv3 Implementation in IBM N/OS

OSPFv3 Differences from OSPFv2

OSPFv3 Requires IPv6 Interfaces

OSPFv3 Uses Independent Command Paths

© Copyright IBM Corp. 2011
OSPF version 3 is based on OSPF version 2, but has been modified to support IPv6
addressing. In most other ways, OSPFv3 is similar to OSPFv2: They both have the
same packet types and interfaces, and both use the same mechanisms for neighbor
discovery, adjacency formation, LSA flooding, aging, and so on. The administrator
must be familiar with the OSPFv2 concepts covered in the preceding sections of this
chapter before implementing the OSPFv3 differences as described in the following
sections.
Although OSPFv2 and OSPFv3 are very similar, they represent independent
features on the G8000. They are configured separately, and both can run in parallel
on the switch with no relation to one another, serving different IPv6 and IPv4 traffic,
respectively.
Note: When OSPFv3 is enabled, the OSPF backbone area (0.0.0.0) is created by
default and is always active.
OSPFv3 is designed to support IPv6 addresses. This requires IPv6 interfaces to be
configured on the switch and assigned to OSPF areas, in much the same way IPv4
interfaces are assigned to areas in OSPFv2. This is the primary configuration
difference between OSPFv3 and OSPFv2.
See "Internet Protocol Version 6" on page 191
Though OSPFv3 and OSPFv2 are very similar, they are configured independently.
They each have their own separate menus in the CLI, and their own command
paths in the ISCLI. OSPFv3 base menus and command paths are located as
follows:
• In the CLI
>> # /cfg/l3/ospf3
>> # /info/l3/ospf3
>> # /stats/l3/ospf3
• In the ISCLI
RS G8000(config)# ipv6 router ospf
RS G8000(config-router-ospf3)# ?
RS G8000(config)# interface ip <Interface number>
RS G8000(config-ip-if)# ipv6 ospf ?
RS G8000# show ipv6 ospf ?
for configuring IPv6 interfaces.
