Usage Information
Before you enable IPsec encryption on an OSPFv3 interface, rst enable OSPFv3 globally on the router. Congure
the same encryption policy (same SPI and keys) on each interface in an OSPFv3 link.
An SPI value must be unique to one IPsec security policy (authentication or encryption) on the router.
When you congure encryption for an OSPFv3 area with the area encryption command, you enable both
IPsec encryption and authentication. However, when you enable authentication on an area with the area
authentication command, you do not enable encryption at the same time.
If you have enabled IPsec authentication in an OSPFv3 area with the area authentication command, you
cannot use the
area encryption command in the area at the same time.
The conguration of IPsec encryption on an interface-level takes precedence over an area-level conguration. If
you remove an interface conguration, an area encryption policy that has been congured is applied to the
interface.
To remove an IPsec encryption policy from an interface, enter the no area area-id encryption spi number command.
Related Commands
• ipv6 ospf encryption – congure an IPsec encryption policy on an OSPFv3 interface.
• show crypto ipsec policy – display the conguration of IPsec encryption policies.
auto-cost
Specify how the OSPF interface cost is calculated based on the reference bandwidth method.
S3048–ON
Syntax
auto-cost [reference-bandwidth ref-bw]
To return to the default bandwidth or to assign cost based on the interface type, use the no auto-cost
[reference-bandwidth ref-bw] command.
Parameters
ref-bw (OPTIONAL) Specify a reference bandwidth in megabits per second. The range is from 1
to 4294967. The default is 100 megabits per second.
Defaults 100 megabits per second.
