I am looking for a switch with a minimum of 12 X 10GE ports on it, that can has routing protocol support and can do GRE in hardware. Does anyone have a suggestion that might fit. Keep in mind I am looking for something in the 1-2U range and not a chassis.

I'd imagine there is no such beast right now. Only one that comes to mind is the 6500/7600 but there is no fixed-configuration small box that fits your port needs, you need a 7604 to get that amount of ports.

juniper mx80 can get 12x10GB using 2x 4x10Gb mics mx platform does gre
in hardware.

appologies it appears only the 2 x 10Gbe mic is supported, so that's 8...
Those are the two options I am looking at now. Unfortunately both of those require the chassis tax and a decent amount of real estate and power. It looks like that is what I am going to be stuck with though because I can't seem to find anyone that has small 1-2U solution that can do the full shake and bake.
Potentially the Cisco 4900M. I can't find specifically about the GRE
support however. My google-fu just finds discussion about v4 to v6
tunnels in software. The chassis has 8 built-in ports and two expansion
modules that can each do another 4 TenG ports in a not-oversubscribed
configuration.

The 4900M doesn't do GRE in hardware.
Extreme 650, but not sure of the gre in hardware req. These are awesome switches, bgp support, VSS like clustering, and many other nice features.

Ugh they're nice except for the power supplies becoming a fireball & they're high dos rate. Ymmv

Gah that should have read doa rate.
@#$@#$ing autocorrect.
sorry about that.

Hard to tell from the data sheet:
http://www.xbridgeservices.com/images/files/7450_ess.pdf
But it looks like the Alcatel-Lucent 7450 ESS-1 might do it. Not sure
if it has 4, 8, or 12 10G ports, though. The data sheet is confusing to
me and it would be oversubscribed but that might be OK in your
applications.
Brocade TurboIron 24X fits all of those criteria.

Last time I checked, the TI24x wouldn't do GRE.

If you don't need "all ports, all-line-rate, all the time" ... you
could rig it with two rack units. I'd dirty it up with something like:
First U: Brocade CER2k 48 (NI-CER-2048CX-ADVPREM-DC) 2x 10 gig + 48 sfp
Second U: Arista 7148SX (DCS-7148SX-R) -- 48x 10 gig
Ridiculous config #1231512:
-take CER 2x 10 gig XFP, configure LAG & trunk host-facing and
transit-facing vlans towards Arista 7148
-configure remaining 46 sfp+ ports as access interfaces for hosts on 7148
-configure static GRE on CER2k, transit neighbors, etc.
-remember to crank mtu's on *
-if box-router traffic is hashable, you could slum it with N x 1gig
port LAG's for more bits/sec between the 7148 and the CER2k
Of course, if two or more hosts are active, chances are good their
inside-tunnel packets won't hash to either side of the 2x10g lag from
the 7148. If your app is using IP in a more i-mix profile, the inner
traffic could then be likewise flow-dense, meaning the hashing will
effectively permit you to utilize all 20 gbits. Arista hashes on
7-tuples, whereas CER is l2+3+4 + labels (if doing mpls, etc), as of
v5.1.
I hear rumors that Brocbroc will be doing 1u N x 10 gig box where N
will hopefully be >= 8 ints... of course, that doesn't help you now.
Lastly, one could employ a 6716 blade + sup720b non-xl (for cheapness)
in 6503E/7603 chassis... but ugh -- 4u, and almost 2x the runtime
wattage of the ghetto-rigged config, and *still* internally
oversubscribed to not-quite-40 gigs per slot!

Brocade TurboIron 24X fits all of those criteria.

It was updated last year -- apparently handled in HW now.
24 ports of 10GE, routing, GRE, and small form-factor = everything the
original inquiry listed.

No, not for TurboIron. FESX, FSX, and SX only in that line of code. It
is a little confusing because the TurboIron uses the same configuration
manual as the other ones I just listed, you have to look closely at the
GRE section (search the doc for 2784 should put you in the right
neighborhood). You will notice that the TurboIron is not mentioned. I
also looked at the release notes up to 4.2.00c and nothing for GRE on
TIX24, in fact, it won't even do PMTUD.
IPv4 point-to-point GRE tunnels
Platform Support: FESX, FSX and SX IPv6 devices running software release
FSX 05.1.00 and later
This section describes support for point-to-point Generic Routing
Encapsulation (GRE) tunnels and
how to configure them on a Brocade device.
GRE tunnels support includes, but is not limited to, the following:
* IPv4 over GRE tunnels. IPv6 over GRE tunnels is not supported.
* Static and dynamic unicast routing over GRE tunnels
* Multicast routing over GRE tunnels
* Hardware forwarding of IP data traffic across a GRE tunnel.
* Path MTU Discovery (PMTUD)
In fact, if you go to Appendix B (RFC Support) on page 1768 there is a
support matrix, you see under RFC 2784 Generic Routing Encapsulation go
across to the TIX column and there is a big fat "NO" there.
Looking at all the release notes in subsequent minor releases shows no
GRE for TIX24
Maybe you have access to a version of code that isn't in GA yet.
