R0106-HP MSR Router Series Layer 3 - IP Routing Command Reference(V7)

191
key-id: Uniquely identifies an SA in the range of 1 to 65535. The sender inserts the Key ID into the
authentication TLV, and the receiver authenticates the packet by using the SA that is selected based on the
Key ID.
hmac-sha-1: Specifies the HMAC-SHA-1 algorithm.
hmac-sha-224: Specifies the HMAC-SHA-224 algorithm.
hmac-sha-256: Specifies the HMAC-SHA-256 algorithm.
hmac-sha-384: Specifies the HMAC-SHA-384 algorithm.
hmac-sha-512: Specifies the HMAC-SHA-512 algorithm.
cipher: Sets a ciphertext password.
cipher-string: Specifies a ciphertext password, a case-sensitive string of 33 to 53 characters.
plain: Sets a plaintext password.
plain-string: Specifies a plaintext password, a case-sensitive string of 1 to 16 characters.
ip: Checks IP-related fields in LSPs.
osi: Checks OSI-related fields in LSPs.
Usage guidelines
The password in the specified mode is inserted into all outbound Level-1 packets (LSP, CSNP, and PSNP)
and is used to authenticate inbound Level-1 packets.
Area authentication enables IS-IS to discard routes from untrusted routers.
Routers in an area must have the same authentication mode and password.
If neither ip nor osi is specified, OSI-related fields are checked.
For security purposes, all passwords, including passwords configured in plain text, are saved in cipher
text.
Examples
# Configure the area authentication mode as simple, and set the plaintext password to 123456.
<Sysname> system-view
[Sysname] isis 1
[Sysname-isis-1] area-authentication-mode simple plain 123456
