And the majority response is "our (vendor) gearcan't handle it". As we both know, Cisco is the largest by far vendor in the marketplace, and I've heard that name more than 70% of the time.Sound like these shops are using 3550 as router, which is common for smaller shops, especially in EU. And indeed, 3550 would not do uRPF. (3560E does).
I don't honestly know. I do know that in every case it was mentioned to me it was either a 6500 or a 7600.
(that it was a Cisco anyway)But frankly, lack of uRPF doesn't mean that BCP38 is impossible. My generation of Force10 gear can't do uRPF. Yet we are BCP38 compliant.
