Usage Information
Before you enable IPsec authentication on an OSPFv3 interface, first enable IPv6
unicast routing globally, configure an IPv6 address and enable OSPFv3 on the interface,
and assign the interface to an area.
An SPI value must be unique to one IPsec security policy (authentication or encryption)
on the router. Configure the same authentication policy (same SPI and key) on each
OSPFv3 interface in a link.
To remove an IPsec authentication policy from an interface, enter the no ipv6 ospf
authentication spi number command. To remove null authentication on an interface
to allow the interface to inherit the authentication policy configured for the OSPFv3
area, enter the no ipv6 ospf authentication null command.

Commands
• area authentication – configure an IPsec authentication policy for an OSPFv3
area.
• show crypto ipsec policy – display the configuration of IPsec authentication
policies.
• show crypto ipsec sa ipv6 – display the security associations set up for OSPFv3
interfaces in authentication policies.
ipv6 ospf bfd all-neighbors
Establish BFD sessions with all OSPFv3 neighbors on a single interface or use non-default BFD session
parameters.
Syntax
ipv6 ospf bfd all-neighbors [disable | [interval interval min_rx
min_rx multiplier value role {active | passive}]]
To disable all BFD sessions on an OSPFv3 interface implicitly, use the no ipv6 ospf
bfd all-neighbors disable command in interface mode..
Parameters
disable (OPTIONAL) Enter the keyword disable to disable BFD on this
interface.
interval
milliseconds
(OPTIONAL) Enter the keyword interval to specify non-
default BFD session parameters beginning with the transmission
interval. The range is from 50 to 1000. The default is 200.
min_rx

Enter the keywords min_rx to specify the minimum rate at
which the local system receives control packets from the
