Jason,

It has been a few years since I have seen SUP2, but I hope I remember
the details...

Sup2 does not support any MPLS based services natively, and the only way
to get MPLS to work on SUP2 is to use an OSM module to terminate the
services on (not just core facing - the whole thing).

With SUP720 you can do native MPLS (without any special line cards) for
L3 VPN and port/sub-if based L2VPN (not SVI).
For SVI based, as well as EVC based MPLS services you need ES/ES+
modules.

I'm looking to potentially use a Sup2 based 6500 as a AToM/EoMPLS PE/LER
with customers terminating on various X6248, X6348, X6516 and X6408A
ports.

Possible?

In a perfect world, port based and VLAN based (the implication being
that interworking support would need to be there too), in either case,
the far end of the VC would be to a NPE-G1 flavored PE/LER of some sort.

Google has shown me configuration example of a Sup2 doing SVI based
EoMPLS, but that confuses the heck out of me because I know that, for
example, in Sup720 land, you can't do SVI based unless you have an ES
card or a SIP.  If this is true and it does actually work, would this
just be the difference between the Sup2 doing it in software vs. the
Sup720/ES|SIP doing it in hardware?

Hoping some people here have some practical experience one way or the
other.

Thanks in advance.
