Information how to configure MFA on Juniper MX

Some customer could have the doubt how to configure MFA on Juniper routers for admin access, customers requested information related.

Juniper routers themselves don't directly support Multi-Factor Authentication (MFA) for logins. However, you can achieve MFA indirectly through an external RADIUS or TACACS+ server. These servers can handle the MFA logic and communicate with the Juniper router for authentication.

Here's a breakdown of the approach:

1. RADIUS or TACACS+ Server: You'll need a server like RADIUS or TACACS+ configured to handle user authentication. This server can integrate with various MFA providers like Okta, Yubico, or even SMS verification.
2. Juniper Router Configuration: Configure the Juniper router to use the RADIUS or TACACS+ server for authentication. This involves specifying the server IP address, shared secrets, and authentication protocols.
3. MFA Provider Integration: On the RADIUS/TACACS+ server, configure the MFA provider you want to use. This involves setting up accounts and following the specific provider's integration steps.

Resources:

• Juniper doesn't have an official guide for MFA on routers, but they do provide documents on using RADIUS and TACACS+ for authentication:
  • RADIUS: Juniper Networks RADIUS Configuration: https://www.juniper.net/documentation/us/en/software/junos/user-access/topics/topic-map/user-access-radius-authentication.html
  • TACACS+: There isn't a specific Juniper guide for TACACS+ configuration, but many resources online cover it. You can search for "TACACS+ configuration Juniper router".
