Version Description
8.3.19.0 Introduced on the S4820T.
Usage Information
Before you enable IPsec encryption 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 encryption policy (same SPI and key) on each
OSPFv3 interface in a link.
To remove an IPsec encryption policy from an interface, enter the no ipv6 ospf
encryption 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 no ipv6 ospf encryption null command.
