Guys I'm trying to make sense out of the attached Cisco Topology

My test environment consists of, various core (P)and distribution(PE) 7600?s (Sup720 without OSM, SIP-600, SPA). Access node consists of a Ethernet DSLAM (although kind of irrelevant at this point).

I?m focusing on layer 2 Access node ? Distribution (Active/backup) Redundancy (No aggregation layer) to two separate distribution PE?s. It seems as though its describing the classic triangular loop, completed by an inter-distribution EoMPLS PW. It then appears as if packets are been forwarded out of the layer 2 domain by an SVI on both distro?s, using HSRP as the floating gateway. The only issue is implementing PW on an interface and assigning an IP address. Unfortunately I cannot use VFI, though I?m not convinced this would help either. I cannot xconnect from an SVI either (due to restriction on non OSM, SPA modules). I?m guessing bridging using irb would be the only feasible solution (if it does work).

1) Am I way off?

2) Would VFI?s help in any way?

3) What would you suggest?

Any information related to this would be extremely useful. Many thanks in advance.
