Well for example, MPLS IP traffic engineering. MLX/XMR is missing nearly every feature that would be necessary to do IP TE in a complex service provider network, its MPLS is basically only useful for doing some simple transport services, meanwhile MX has one of the best MPLS implementations available anywhere. If you don't need MPLS or you don't need TE than it really doesn't matter to you. If on the other hand you run a complex network TE can save you millions in circuit costs, and there is absolutely no comparison between the two products. Another example would be complex BGP policies. For example, we use Juniper commit scripts and netconf to automatically build all manner of BGP policies (auto per-ASN bgp communities, lots of ibgp cross-region policies, etc), providing automation that saves us many thousands of man hours that other large networks have to put into maintaining their network. Foundry doesn't even support route-map continue, so it is nearly impossible to build powerful policies using it. If you have a simple network without complex policies or bgp communities it may not matter to you, but if you have a complex network there is again just no comparison. :) There are plenty of other things that may or may no tmatter to you, complex vlan rewrite and double-tag functionality that Foundry can't do, advanced firewall features, things like that. Lack of /31 support and inability to measure usage on routed vlans until the latest generation of 8-port 10GE cards should probably be somewhere high on the list too. Personally I wouldn't trade my MX's for XMR's even if they were free, but if none of the above sounds like something you do then MLX/XMR may be fine for you. Then again, you may want to compare it to Juniper EX instead. EX is a lower end switch platform that doesn't do a lot of things that MX does, but it's much closer to MLX functionality and they're running some dirt cheap EX promo pricing right now. -- Richard A Steenbergen <[email protected]> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC) _______________________________________________ foundry-nsp mailing list [email protected] http://puck.nether.net/mailman/listinfo/foundry-nsp
