The output shows that the host public key of Router A saved on Router B is consistent with the one
created on Router A.
Importing a public key from a public key file
Network requirements
As shown in Figure 77, to prevent illegal access, Router B (the local device) authenticates Router A (the
peer device) 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 to authenticate Router A.
• Import the host public key of Router A from the public key file to Router B.

Configuration procedure
1. Create key pairs on Router A and export the host public key:
# Create a local RSA key pair with the default name and the default modulus length of 1024 bits.
