Configuring a manual IPsec profile

An IPsec profile is similar to an IPsec policy. The difference is that an IPsec profile is uniquely identified
by a name and it does not support ACL configuration. An IPsec profile defines the IPsec transform set
used for protecting data flows, and specifies SPIs and the keys used by the SAs.
The IPsec profile configurations at the two tunnel ends must meet the following requirements:
The IPsec transform set referenced by the IPsec profile at the two tunnel ends must have the same
•
security protocol, encryption and authentication algorithms, and packet encapsulation mode.
The local inbound and outbound IPsec SAs must have the same SPI and key.
•
• The IPsec SAs on the devices in the same scope must have the same key. The scope is defined by
protocols. For OSPF, the scope consists of OSPF neighbors or an OSPF area. For RIPng, the scope

N/A
By default, the interface uses the
global DF bit setting.
Remarks
N/A
By default, IPsec copies the DF bit
in the original IP header to the
new IP header.
