Changing OSPFv2 Parameters on Interfaces
In Dell Networking OS, you can modify the OSPF settings on the interfaces.
Some interface parameter values must be consistent across all interfaces to avoid routing errors. For example, set the same time interval
for the hello packets on all routers in the OSPF network to prevent misconfiguration of OSPF neighbors.
To change OSPFv2 parameters on the interfaces, use any or all of the following commands.
•
Change the cost associated with OSPF traffic on the interface.
CONFIG-INTERFACE mode
ip ospf
cost
•
cost
: The range is from 1 to 65535 (the default depends on the interface speed).
•
Change the time interval the router waits before declaring a neighbor dead.
CONFIG-INTERFACE mode
ip ospf dead-interval
seconds
•
seconds
: the range is from 1 to 65535 (the default is
40 seconds
).
The dead interval must be four times the hello interval.
The dead interval must be the same on all routers in the OSPF network.
•
Change the time interval between hello-packet transmission.
CONFIG-INTERFACE mode
ip ospf hello-interval
seconds
•
seconds
: the range is from 1 to 65535 (the default is
10 seconds
).
The hello interval must be the same on all routers in the OSPF network.
•
Use the MD5 algorithm to produce a message digest or key, which is sent instead of the key.
CONFIG-INTERFACE mode
ip ospf message-digest-key
keyid
md5
key
•
keyid
: the range is from 1 to 255.
•
Key
: a character string.
NOTE:
Be sure to write down or otherwise record the key. You cannot learn the key after it is configured. You must be
careful when changing this key.
NOTE:
You can configure a maximum of six digest keys on an interface. Of the available six digest keys, the switches
select the MD5 key that is common. The remaining MD5 keys are unused.
