I thought the 7600 MPLS functionality was severely limited - could only act as a core, not edge device or similar? (I forget the details)

(We're deploying 7600s next month, MPLS won't be needed immediately but we'll need it in around 6 months time - was planning to use 7200s at the edge)

AFAIK, it depends on the supervisor. AFAIK 3B and 3BXL give you full MPLS VPN P/PE functionality (more VRFs/routes per VRF on the 3BXL). Original Sup720 does not. Sup2 doesn't either.

To clarify the situation:

Sup720 (3a) does support basic MPLS functionality (backbone MPLS and L3 MPLS VPN), but some internal HW bug can cause problems especially if you use with IPv6. This cannot be resolved therefore if you need MPLS you MUST use Sup720-3b or sup720-3bxl. Officially Cisco support MPLS only on Sup270-3b(xl) on sup720 type platforms. One problematical point is L2 MPLS VPN, which is supported only with OSM modules. For the Sup2 platform you must have OSM modules for MPLS funtionality, since MPLS is implemented on OSM interface cards on Sup2 platform.

We are using 8 C6500 with Sup720-b (some bxl) without much problem for peering routers for IPv4 uni/multicast and IPv6 unicast (12.2(18)SXD3). The IOS has some very nusty bug that can crash the whole router.... We are using L3 MPLS VPNs rather widely.

PPS is rather acceptable we use some places DFC-3 modules. We use only rate-limiting of QoS functions whihc works well. Hardware based uRPF works too.

We also use Netflow, and that works well

For now, we're keeping 7200/7500 routers for MPLS.
