I have a 3com 4500 connected to 2 5500s (A & B), which are the the GWs for the 4500. I issued on the 4500: ip route-static 0.0.0.0 0 192.168.0.254 preference 60 (5500 A) ip route-static 0.0.0.0 0 192.168.0.253 preference 70 (5500 B) on dis ip routing-table verbose, both routes appear but the preference 70 shows as inactive. The idea is, if .254 goes down, the 4500 would find the preference 70 route to keep its work but, in practice this is not happening. If I turn off .254, my machines on the 4500 loose connectivity. How can I make this work? i.e. make both routes active?

Please specify more the problem.

Assign a static ip on your host machines.

The last part of the IP address has to be more than 10 apart. That is to say: if your first address is 193.156.36.90 then your second should be 193.156.36.100 or higher or 193.156.36.80 or lower. I like to go for 50 higher or lower then you are well out of the range of your main router.

Do the nslookup for the three websites and write an access list to permit the traffic only to the said website ip addresses

Eg.

1. go to dos prompt

2. type "nslookup"

3. type "www.rediff.com

Note : You will get the ip address of the websites

4. Create an object group for these websites

5. Add ip addresses of the websites

6. create an access-control list element to permit the traffic from your circle office to this object group for port tcp 80 and 443

You are done

A router will be the best device that can share that static ip that you have from your vendor. Router's will have an option to set it's internet connectivity to static ip and you will just need to put in the static ip address, SM, Default gatewa, and DNS servers from you vendor. And the router will do the rest.

i can't set ip address over 4 vlans. the 3com switch 4500 always give error message "there's not enough routing resources available".please help....
