[c-nsp] Why does the ME3600X not support VLAN mapping?

Hi all, I am somewhat confused/annoyed by the ME 3600X's lack of support for VLAN mapping. The ME-C3750 offers this, listing the feature as metro Ethernet service for obvious reasons. I would go as far as saying that this is, in fact, a requirement for a device sold as offering ME capabilities.

DHCP servers could care less about who you are. They will give out an address to just about anyone. Now MBA or 802.1x authentication can be used to block this. With MBA or 802.1x you could place the authenticated users in to a different vlan, where all of your domain related information resides.

From the limited details, it sounds like what you really want is vrf-lite. Assuming the application traffic can be split into its own subnetwork, stick them in a VRF whose normal routing table matches what you're forcing via PBR. On Mar 6, 2012, at 6:55 PM, Zach Williams
