Enter global configuration mode.
Raisecom(config)#router

[ router-id
router-id

Enable an OSPF process and enter OSPF
configuration mode.
Raisecom(config-router-
ospf)#timers spf
delay-time
hold-time
Configure the calculation delay and
interval of the OSPF route.
By default, the calculation delay is 2s and
the calculation interval is 3s.
Configuring OSPF passive interface
To prevent some OSPF routing information from being obtained by some routers on the
network, you can configure the interface to an OSFP passive interface to disable the interface
to send OSPF packets.
Configure the OSPF passive interface for the ISCOM2600G-HI series switch as below.
Enter global configuration mode.
Raisecom(config)#interface
interface-type
interface-number
Enter interface configuration mode.
Raisecom(config-
gigaethernet1/1/port)#ip ospf
passive-interface enable
Enable passive interface on the
OSPF interface.
By default, it is disabled.
Configuring MTU ignorance
By default, the value of MTU domain in the DD packet is the MTU value of the interface,
which sends the DD packet. Default MTU values may vary on devices. In addition, if the
MTU value of the DD packet is greater than the one of the interface, the DD packet will be
discarded. To ensure receiving the DD packet properly, enable MTU ignorance to configure
the MTU value to 0. Therefore, all devices can receive the DD packet.
Configure MTU ignorance for the ISCOM2600G-HI series switch as below.
Enter global configuration mode.
Raisecom(config)#interface
interface-type
interface-
number
Enter interface configuration mode.
Raisecom(config-
gigaethernet1/1/port)#ip
ospf mtu-ignore enable
Enable MTU ignorance on the IP interface.
By default, MTU ignorance is disabled on
the IP interface to check MTU of the
OSPF Hello packet.
