Installing Software When a Firewall Exists
ERX Edge Routers
E-3
9 Install the software release file to the system space on the ERX
system.
10 Save the current configuration.
11 Reboot the system.
Task 1: Obtain the Required Information
Before you install the software, obtain the following information:
• The password (if one is configured) that allows you to access Privileged
Exec mode on the ERX system
• The IP address of the network host
• The IP address of the ERX system
• The IP address of the next hop to reach the destination network (for
example, a gateway)
• The login name and password for the vty line
• The procedure for mounting a CD on the network host
Task 2: Access Privileged Exec Mode
To access this mode via the CLI:
1 Issue the enable command.
host1>enable
2 Type the password if the system prompts you.
Task 3: Configure IP on an Interface
Typically, you configure IP on the Fast Ethernet interface of the SRP
module. To configure IP on an interface:
1 Determine the slot number of the module.
host1#show version
2 Determine the port number of the module.
3 Determine whether the interface already has an IP address.
host1#show ip interface fastEthernet 6/0
Note: If an IP interface is not configured, you see the message “Invalid interface.”
If the interface already has an IP address, go to step 5. Otherwise,
proceed with step 4.
