Understand Default Forward Groups

Greetings all,

  So i am trying to understand default forward X and if using the same default forward X number on different VIPs using the different CSW policies have any conflict at all.  I am not sure I am going to ask the question correctly but I will try

 

If I have two VIPs and each points to a different CSW Policy and then each VIP points to two different Servers but the servers are all configured with the same group-id, is there any potential conflict?

 

server virtual VIPone 10.10.10.1
sym-priority 50
port http sticky
no port http translate
port http use-alias-port-state
port http reset-on-port-fail
port http lb-pri-servers
port http csw-policy "test1"
port http csw
port http keep-alive
bind http rs1 http rs2 http


csw-policy "test1" 
match "Support" redirect "www.myurl.com" "/support" ssl 
default forward 1
default rewrite request-insert client-ip "X-Forwarded-For"

server real rs1 1.1.1.1
source-nat
port http
port http use-port-policy test
port http keepalive
port http url "HEAD /"
port http group-id 1 1

server real rs2 1.1.1.2
source-nat
port http
port http use-port-policy test
port http keepalive
port http url "HEAD /"
port http group-id 1 1

 

server virtual VIPtwp 20.20.20.1
sym-priority 50
port http sticky
no port http translate
port http use-alias-port-state
port http reset-on-port-fail
port http lb-pri-servers
port http csw-policy "test2"
port http csw
port http keep-alive
bind http rs3 http rs4 http


csw-policy "test2" 
match "Support" redirect "www.myurl.com" "/support" ssl 
default forward 1
default rewrite request-insert client-ip "X-Forwarded-For"

server real rs3 2.2.2.1
source-nat
port http
port http use-port-policy test
port http keepalive
port http url "HEAD /"
port http group-id 1 1

server real rs4 2.2.2.2
source-nat
port http
port http use-port-policy test
port http keepalive
port http url "HEAD /"
port http group-id 1 1

 Even though rs1, rs2, rs3, rs4 are configured with the same group-id, because they are configured for different VIPs with different CSW Policies, there should not be any conflicts correct?  

 

For the most part our VIPs point to dedicated servers.  There might be multiple servers that are all load balancing, so they can all be in group-id 1 but I am trying to streamline our configs and currently for every VIP, we change the group-ids but there come points where, based on the VIP number, that the group-ids can be the same and would lead the enginner to use a group-id that is already in use.  I think that is ok, but trying to validate.  I can clarify more if necessary.

 

Thanks

Wally
