3.1.40 ospf cost
Syntax
ospf cost value
undo ospf cost
View
Interface view
Parameters
value
: OSPF cost, in the range 1 to 65535.
Description
Use the
ospf cost
command to set an OSPF cost for the interface.
Use the
undo ospf cost
command to restore the default OSPF cost for the interface.
By default, an OSPF interface calculates its cost with the formula: interface default
OSPF cost=100 Mbps/interface bandwidth(Mbps). Default OSPF costs of some
interfaces are:
z
1785 for the 56kbps serial interface
z
1562 for the 64kbps serial interface
z
48 for the E1 (2.048Mbps) interface
z
1 for the Ethernet interface
You can use the
ospf cost
command to set an OSPF cost for an interface manually.
This configuration is not supported on the NULL interface.
