R3303-HP HSR6800 Routers Security Command Reference

311
• Within a certain network scope, each router must use the same SPI and keys for its inbound and
outbound SAs, and all routers must use the same SPI and keys. For OSPFv3, the scope can be
directly connected neighbors or an OSPFv3 area. For RIPng, the scope can be directly connected
neighbors or a RIPng process. For IPv6 BGP, the scope can be directly connected neighbors or a
neighbor group.
Examples
# Set the SPI for the inbound SA to 10000 and that for the outbound SA to 20000 in a manual IPsec
policy.
<Sysname> system-view
[Sysname] ipsec policy policy1 100 manual
[Sysname-ipsec-policy-manual-policy1-100] sa spi inbound ah 10000
[Sysname-ipsec-policy-manual-policy1-100] sa spi outbound ah 20000

Use undo sa string-key to remove the configuration.

2: System level
Parameters
inbound: Specifies the inbound SA through which IPsec processes the received packets.
outbound: Specifies the outbound SA through which IPsec processes the packets to be sent.
ah: Uses AH.
esp: Uses ESP.
cipher: Sets a ciphertext key.
simple: Sets a plaintext key.
string-key: Specifies the key string. This argument is case sensitive. If cipher is specified, it must be a
ciphertext string of 1 to 373 characters. If simple is specified, it must be a string of 1 to 255 characters.
If neither cipher nor simple is specified, you set a plaintext key string. For different algorithms, enter
strings of any length in the specified range. Using this key string, the system automatically generates keys
meeting the algorithm requirements. When the protocol is ESP, the system generates the keys for both the
authentication algorithm and encryption algorithm.
For security purposes, all keys, including keys configured in plain text, are saved in cipher text to the
configuration file.
