Hurray! Er, what was the question again?
Kidding. Right Instead of the two points of failure solution, is it possible to: 1) Have the Cisco router as the default route for subnet1 2) Have the following routing table on the Cisco: Arbitrary numbers: subnet1 = 10.1.0.0/16 subnet2 = 10.2.0.0/16 subnet3 = 10.3.0.0/16 subnet4 = 10.4.0.0/16 Cisco1 = 10.1.0.1 LEAF box = 10.1.0.2 Source Dest Gateway 10.1.0.0/16 10.2.0.0/16 10.2.0.1 10.1.0.0/16 10.3.0.0/16 10.3.0.1 10.1.0.0/16 10.4.0.0/16 10.4.0.1 10.1.0.0/16 default 10.1.0.2 Which is a backwards two points of failure solution. But the two points of failure, the Cisco and the LEAF box, are between subnet1 and the internet, not subnet1 and subnetN. And the internet is less important than the inter-site connectivity. Bearing mind I don't know anything about these Cisco things. They run on voodoo as far as I know. OR Throw away the Cisco and just use LEAF! :D Regards, James. -----Original Message----- From: Robert K Coffman Jr - Info From Data Corporation [mailto:[EMAIL PROTECTED] Sent: 28 June 2005 15:32 To: James Neave; [email protected] Subject: RE: [leaf-user] Network Configuration Ideas Right on!

If there were two routers in subnet1, one to the internet (LEAF) and one to the other subnets (Cisco), then two routes would have to be added to the client machines and you don't want that (sounds nasty)? Whereas if you made the LEAF box route the traffic from subnet1 to subnet2 via the Cisco you would have 2 points of failure for traffic between the LEAF box and the Cisco. But this would give you one default route on the client boxes which is really what Windows likes. Now do I get you?

Exactly. As much as I know that Leaf is completely capable of performing this function, it just introduces another failure point to their network that I don't want.

When you say you don't want LEAF as a single failure point, do you mean you don't want LEAF to be a NAT'ing firewall for you internet connection as well as performing the routing and/or tunnelling between your subnets?

I didn't want to put this on list, because it isn't a Leaf question per se, however I'm struggling with what to do with this. In the simplest terms possible, I have a 4 subnet network, with each subnet at a different physical location. Location 1 has the internet connection, and the "core server" (read:Citrix) for all the other locations. Internet connectivity is via a proxy server on the location 1 subnet. I would like to eliminate the proxy, and replace it with Leaf with no proxy. The problem is, is that this would give anyone in Location 1 two routes off their network. The connections to the remote subnets are via T1 and they all connect to location 1 via a Cisco router which has no free connections. Must have goals: eliminate proxy server, provide one route off of the Location 1 subnet. Would like goals: Avoid having Leaf as failure point between subnet 1 and the remote subnets. Avoid purchasing a new Cisco router. Unfortunately, it seems that my best option would be to put another adapter in the Leaf router, and renumber subnet 1, so that everything converges at leaf on the old subnet 1 address. However, since I'm using old commodity hardware for that task, and internet connectivity is less important to the business than the connectivity between the locations, I would love to keep this from becoming a point of failure. Any ideas on what to do here? Or have I exhausted my options and I need to violate one of my "would like" goals? I don't know Cisco, but I suspect if I did I could make short work of this problem. - Bob Coffman The information in this email is confidential and may be legally privileged.
