Public key configuration examples
Configuring a remote host's public key manually
Network requirements
, to prevent illegal access, Router B authenticates Router A through a digital
signature. Before configuring authentication parameters on Router B, configure the public key of Router
A on Router B.
•
Configure Router B to use the asymmetric key algorithm of RSA for identity authentication of Router
A.
•
Manually configure the host public key of Router A on Router B.

The range of public key size is (512 ~ 2048).
NOTES: If the key modulus is greater than 512,
It will take a few minutes.
Press CTRL+C to abort.
