Predefined user roles
network-admin
Parameters
inbound: Specifies an SPI for inbound SAs.
outbound: Specifies an SPI for outbound SAs.
ah: Uses AH.
esp: Uses ESP.
spi-number: Specifies a security parameters index (SPI) in the range of 256 to 4294967295.
Usage guidelines
This command applies only to manual IPsec policies and IPsec profiles.
You must configure an SPI for both inbound and outbound SAs, and make sure the SAs in each
direction are unique: For an outbound SA, make sure its triplet (remote IP address, security protocol,
and SPI) is unique. For an inbound SA, make sure its SPI is unique.
The local inbound SA must use the same SPI as the remote outbound SA, and the local outbound SA
must use the same SPI as the remote inbound SA.
When you configure an IPsec policy or IPsec profile for an IPv6 routing protocol, follow these
guidelines:
•
The local inbound and outbound SAs must use the same SPI.
•
The IPsec SAs on the devices in the same scope must have the same SPI. The scope is
defined by protocols. For OSPF, the scope consists of OSPF neighbors or an OSPF area. For
RIPng, the scope consists of directly-connected neighbors or a RIPng process. For BGP, the
scope consists of BGP peers or a BGP peer group.
Examples
# Set the SPI for the inbound SA to 10000 and the SPI for the outbound SA to 20000 in a manual
IPsec policy.
