Multihop eBGP across Transparent Firewall

[j_a_m_e_s]

Dear All

I would like to run eBGP across an FGCP pair (A-P mode) with a transparent vdom. Could you take a look at my diagram and let me if this looks feasible please? My questions are:

1. Is my addressing with a /29 subnet ok and a single manage-ip to be shared by the FW pair's transparent vdom?

2. Should the same vlan 100 be stretched across all the switches?

3. If the answer to 2) is yes would i need to allow Spanning-Tree and which would be the blocked port?

Any help would be greatly appreciated.

James.
