Processing process: The Juniper SRX Series firewall is based on the Juniper Jnos system. Initial login username is root and password respectively null. Change your password first after entering. The order is as follows: Root> Root> Configure Entering configuration mode [Edit] root# root# Set System Root-authentication Plain-text-password root# New password:jun20110101 root# Retype New password:jun

1 Juniper Router enters configuration mode for the first time, you must set the login password, or the commit prompts for a root-authentication password, and the login password method is set as follows: Root#set system Root-authentication Plain-text-password New Password: (the password here must be a combination of numbers + letters, at least 6 digits) Retype new Password: After the setup is complete, the root login password is set successfully.

Juniper to implement the redistribution function like Cisco is to be implemented by policy, here is an example of me: its function is to distribute static routes to OSPF, the following is the topology map Redistribution of R1 default routes into OSPF The configuration is as follows: # # # # Last changed:2012-07-18 06:03:09 CST version 12.1r1.9; Logical-systems {r1 {interfaces {em1 {unit 12 { Vlan-id

Problem description: When the SSG series firewalls of Juniper can access each other through VPN dial-in or direct mutual access between different network segments, sometimes PING can be reached, but the service cannot be accessed, such as WEB and shared files. Problem Analysis: These problems are often caused by the identification of data packet fragments by devices during data transmission. Generally, data packets are too large and nee
