OpenROUTE 3.3
Release Notes

CAUTION:

You need to be aware that when you load a .rap file onto your router, the .rap file erases any files you previously saved in your IBD and it can also overwrite your current configuration.

To preserve

files stored in your IBD, copy those files to another location before you load the new software onto your router. You can use TFTP to copy those files.
your existing configuration, answer Yes when you load the .rap file onto your router and the software prompts you for whether you want to save your existing configuration.

If you do not choose to save your existing configuration, you need to configure your router from the beginning when the router completes the update of the boot code and load image.

The following are the prompts you see when you load a .rap file.

Overwrite Current Boot Code and Load File? [Y/N] Y
Any files you have stored on your IBD will be erased.
Are You Sure (Confirm)? [Y/N] Y
Keep Current Configuration? [Y/N] N
Are you sure you want to erase the current configuration (Confirm)? [Y/N]

3.0 Corrected Problems

The following problems have been corrected since the OpenROUTE 3.2.2 software release.

3.1 RADIUS Authentication Software

The RADIUS server previously used port 1645, which conflicts with the Datametrics service. The assigned port number is now 1812, and the router software defaults to 1812.

There is a new option for the add server and set server Authentication commands that lets you change the port number if you need the router to communicate with older RADIUS servers that still use port 1645. For example, to add a RADIUS server that communicates with the router over port 1645, enter
```
Auth Config>add server 128.185.123.1 port=1645
```
During challenge/response authentication, the RADIUS server may send a State Attribute that the router, as a client, must always send back with the challenge response. Previously, the router always set this field to 1 regardless of what the server sent. The router no longer changes the State Attribute. It returns the State to the server unchanged.

4.0 Known Deficiencies, Limitations, and/or Clarifications

This section describes known deficiencies in OpenROUTE 3.3 and indicates limitations with the software.

4.1 General

GT 60 Series, GT 70 Series, and GT 100 routers do not have a time of day clock chip with battery backup. For time to be meaningful, you have to get the time from a nearby host or manually set the time. The time commands at the Config> prompt allow for these operations. Enter time set at restarts or set up the time configuration to poll a nearby host.

4.2 DDS Module

If you connect a DDS module back-to-back with a DDS module in another router for testing purposes, the ALM (Alarm) LED comes on because no loop current is generated in this configuration. Tests will run normally despite the lack of loop current, so you can ignore the LED in this situation.
The DDS software does not have a separate ELS subsystem. Message 47 in Serial Line (SL) ELS subsystem applies to DDS modules.

4.3 DHCP Client

You cannot set up Frame Relay LAN Emulation (FRLANE) interfaces as DHCP clients.
When a DHCP lease is in the rebind state, the state still displays as the renewal state. This does not affect the operation of DHCP client.

4.4 DHCP Server

If you set a domain name that the DHCP server assigns using the set domain-name command, there is no way to set the domain name back to the default of none. To clear the domain name, you must clear the complete DHCP Server configuration.
When you enter list interface at the DHCP Server> prompt, the software does not always display the correct number of clients bound to the server. To see a list of clients bound to the server, enter list all at the DHCP Server> prompt.

4.5 GT 60 Series

When all of the following conditions occur on a GT 60 Series router, the router hangs when you reload the router software. If this happens, you must cycle the power on the router to get the router running again.

An RS232 DTE cable, X.21 DCE cable, or X.21 DTE cable is plugged into the router's WAN port, but not connected at the other end.
The line discipline in the Serial Line configuration is set to async.
The Serial Interface Dialer (DIAL) is enabled.

4.6 GT 70 Series

The console port on GT 70 Series routers does not support autobaud. The baud rate defaults to 9600, but you can change it using the set baudrate configuration command.
When the GT 70 Series router is booting, the LAN and the OK status lights both blink. Only the OK light should blink.

4.7 GTX 1500 With PPP Data Compression

If you are running PPP data compression on the GTX 1500 platform and you send data that is incompressible, the router may crash with a "trailing guard word corrupted" message. This happens if the end application builds data packets that fill the PPP MTU completely.

To work around this problem, increase the global buffer size, which provides more trailer buffer space for PPP compression. To do so, use the following command. OpenROUTE Networks recommends setting the buffer size to 2048.

Config>set packet-size 2048

4.8 GTX Series

Before you install a new module in your GTX Series router, be sure that you have the appropriate BOOT and router software.

If you are installing a new module that is not one of those listed below, go to the OpenROUTE Networks Customer Support Web site:

www.openroute.com/service/index.html

On the Web site, is a table called "GTX Series Modules" that lists the currently available GTX Series modules and their BOOT and router software versions.

4.9 IP Tunnels

IP Tunnels require a single Maximum Transfer Unit (MTU) size across all remote destinations. This single size must be the smallest MTU required across all remote destinations. The MTU discovery feature dynamically determines the MTU size to use on IP Tunnels. By default, MTU discovery is enabled, and OpenROUTE Networks recommends that you do not disable MTU discovery.

If your tunnel is running over a PPP interface and you disable MTU discovery, make sure the Maximum Receive Unit (MRU) size in PPP is at least 100 bytes larger than the MTU of the tunnel. The default MRU size in PPP is 1500 bytes.
To avoid problems due to incorrect MTU/MRU sizes, OpenROUTE Networks recommends that you use the default settings.

The IP Tunnel software lists IP Tunnel interfaces as Up even though they may be Down. To see an accurate list of IP Tunnels that are Up, enter list receive parameters at the SKIP NET-#> prompt. If the tunnel is Down, the algorithm entries display UNKNOWN.

SKIP NET-6>list receive parameters
                        Received Packet Parameters

Destination     Master     Bulk       Auth       Comp        Drop    
                Algorithm  Algorithm  Algorithm  Algorithm   Unsigned  
misty           DES-CBC    DES-CBC    MD5        STAC-LZS    NO

4.10 ISDN and Quick Configuration

The GT 70 Series Quick Config does not ask for directory numbers for the INS64 switch variant because INS64 does not require them. Therefore, if the INS64 switch needs subaddressing, you must enter the ISDN configuration and explicitly set the directory numbers.

Config>network 1
Circuit Configuration
Circuit Config <NET-1> bri
Basic Rate ISDN user configuration
BRI Config <NET-1> set dn0
Enter DN0 (Directory-Number-0) []? :54

Note: Directory number 0 (DN0) only has a subaddress component which, in this example, is 54.
