[问题分析] NS 208 - Source-Based Routing

I have a Netscreen 208. I added an additional router to it. We currently have 2 ISP's.
I have the following Example and it Works fine: tIbpkxy-  
All traffic goes out E7. (please ignore E8)


Trusted

E1 192.168.1.0 /23

E2 192.168.3.0 /24

E3 192.168.4.0 /24

Untrusted

E7 1.1.1.0/28 "
E8 2.2.2.0/28 (please ignore E8)

Routing Table: All set to Metric 0.

E1 192.168.1.0 /23 default gw 0.0.0.0

E2 192.168.3.0 /24 default gw 0.0.0.0

E3 192.168.4.0 /24 default gw 0.0.0.0


E7 0.0.0.0/0     default gw 1.1.1.1

E8 0.0.0.0/0     default gw 2.2.2.2  

What I would like to happen is Add the following:

E4 192.168.5.0 /24 default gw 0.0.0.0

E6 0.0.0.0 /24     default gw 3.3.3.3 1
Have all E4 taffic go out E6


But, when I setup a route in the routing table. as follows: 192.168.5.0 Default GW 3.3.3.3 everything goes out E7.
I am currently on Ver. 4.03 on the netscreen. I’m not sure if ver. 5.0 fixed any source-based routing issues. Because, from what I have found, is the following:

http://kb.juniper.net/CUSTOMERSERVICE/index?page=kbdetail&record_id=0244022611e8310108012c3c1901d73

Ver. 5.0 shows source-based routing as an option in the WEBUI. However, the article says it for ver. 4.0 and above. On my netscreen, source-based routing is not an option in the WEBUI. But, it is an option from the CLI. And enabling source-based routing from the CLI doesn’t seem to work. Then again, I could have configured it wrong.

Moreover, I am afraid to go ver 5.0. Because, we did that once before and it crashed the Netscreen.

Thank you for you help.
