10 OSPFv3 Routing
NOTE: All commands previously in the Summary of commands table are indexed under the entry
Command syntax.
OSPFv3 is the IPv6 implementation of open shortest path first protocol. (OSPFv2 is the IPv4
implementation of this protocol.) Beginning with software version K.15.01, the switches can be
configured to run OSPFv3 either alone or simultaneously with OSPFv2. (OSPFv3 and OSPFv2 run
as independent protocols on the routing switch and do not have any interaction when run
simultaneously.)
NOTE: License Requirements — In the 3500, 3500yl, 5400zl, 6600, and 8200zl switches,
OSPFv3 is included with the optional Premium License. In the 6200yl switches, this feature is
included with the base feature set.
This section describes OSPFv3 terms, basic features, and general operation. Both VLANS and
tunnels can be assigned to areas and may be collectively referred to as an IP routing interface.
For specific configuration information, turn to the topics referenced in the following command
index.
NOTE: In this chapter, "OSPF" refers to OSPFv3 for IPv6 operation unless otherwise stated.
OSPFv3 RFC compliance
The OSPFv3 features covered comply with the following:
• RFC OSPFv3 for IPv6
• RFC 3101 option
Activating OSPFv3
After either an IPv4 loopback address or a router ID has been configured on the routing switch,
OSPFv3 activates when enabled with the following two commands:
HP Switch(config): ipv6 unicast-routing
HP Switch(config): router ospf3 enable
NOTE: The router ospf3 enable command enables OSPFv3 without a system reset.
Configuring OSPFv3 on the routing switch
Router ID or IPv4 loopback address requirement
OSPFv3 routing requires either a router ID or an IPv4 loopback address configured on the routing
switch. If this requirement is not already satisfied, use one of the following commands to configure
a router ID or IPv4 loopback address:
Syntax:
ip router-id ip-addr
interface loopback 0 - 7 ip address n.n.n.n
ip router-id ip-addr
Executed at the global configuration level to assign a router ID to the routing
switch.
Default: Disabled
