Localdirector and load balancing web pages

tbithoney

Level 1

I have a LD 417. I need to load balance 2 web sites(Real servers) with 1 virtual IP. So, I followed the book "Configuring HTTP redirection on Local Director". It says "To use HTTP redirection to load balance between real machines..."

I setup the DNS.

So, When I open a browser to access the virtual site

I get this page is not avail. I can access the indivual server/sites though...

The config:

virtual 195.100.100.191:80:0:tcp is

real 195.100.100.195:80:0:tcp is

real 195.100.100.196:80:0:tcp is

direct-ip 195.100.100.195:80:0:tcp 195.100.100.195:80:0:tcp is

direct-ip 195.100.100.196:80:0:tcp 195.100.100.196:80:0:tcp is

url abdul http://abdul.tony.com/%p 302

url m300 http://m300.tony.com/%p 302

backup 195.100.100.195:80:0:tcp 195.100.100.191:80:0:tcp

backup 195.100.100.196:80:0:tcp 195.100.100.191:80:0:tcp

name 195.100.100.195 abdul.tony.com

name 195.100.100.196 m300.tony.com

bind 195.100.100.195:80:0:tcp 195.100.100.195:80:0:tcp

bind 195.100.100.196:80:0:tcp 195.100.100.196:80:0:tcp

Right out of the book (With my test domain IP's)

What am I missing/doing wrong?

if you don't need redirection (which is being used to achieve some sort of sitckyness), you can remove the direct-ip,url,backup and name commands.

Just keep the virtual, real and bind.

Also, make sure the next-hop for the real server is a gateway that is accessible through the localdirector

(try to ping a remote ip address from the real server)

Try to ping the virtual from a client PC.

Also capture command to show the status of the virtual and reals.

Capture commands to check arp entries.

Finally capture a sniffer trace to see what is going on.

ok..

-I cannot ping the virtual IP from a PC (I was able to on Friday)

-I can ping the LD 417 IP Address

-I cannot ping an outside addr fron the LD 417

-I can ping the same addr successfully from a PC

I am not sure on the capture commands....sorry...

Thanks...

Giles

an Update:

I now can ping the VIP and web site..

I still cannot ping an outside addr off the LD.

If I use the HTTP redirection (1 vip 2 real) this should load balance the servers...correct?

Tony

Have you setup the ROUTE in your LD yet?

I had a similar problem. I was told to set the ROUTE to my default gateway on that subnet and after doing this, my problem was resolved.

yes i did.

i resolved the issue. i discovered that the addresses were non-routeable. when i used addresses in our dmz, it worked great.

thanks for the feedback!
