What sort of GRE performance should I see from those? GRE is not supported on the small Catalyst switches. It does work (in some versions?) but only at low performance and with high CPU utilization... And, again, it's not supported. Yeah - I've since found that on the Cisco website. But, what about GRE performance on true routers?

But it won't verify the source address on GRE packets it receives, which makes it feasible to forge GRE packets without forging the source address, which in some configurations makes some attacks easier.

[c-nsp] IS-IS or OSPF as IGP?
Hi list, We're redesigning a small MPLS Network (about 30 PE Routers and 2 P Routers -Link between P-PE: Ethernet-), so far the IGP is OSPF, however ISIS was proposed too. What is the best? IS-IS or OSPF? and Why? regarding the small network. Thank you for your suggestions...

Possibly the single most annoying difference is that Cisco uses the command ip router isis tag to activate isis on an interface, vs just ip ospf with no router. Now imagine you're tired and trying to take isis off an interface, and instead of typing no ip router isis you accidentally type no router isis, and guess what happens. :) -- 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) ___ cisco-nsp mailing list cisco-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
