Answering my own question, CSCub58582: BGP traceback - [VPNv4 Unicast] 100:4:203.3.3.0/24 has no local label.
Symptom: When 7K establishes a session with an eBGP VPNV4 peer in the same Confederation, the 7K(s) drops all it's BGP sessions Conditions: 7K has iBGP VPNv4 sessions with peers in an AS. All the peers are members of a Confederation. Session is established and BGP Labels are advertised by the 7Ks for the VPNv4 prefixes in the various VRFs. When a session to an eBGP VPNv4 peer in the same Confederation and the session is established, the 7K(s) drops all it's BGP sessions with BGP-related tracebacks Workaround: None. Not scheduled for fix until 6.1(4) or 6.2. We are having to install a couple of confederation "route reflectors" to work around this. (Why do I feel like a Cisco N7K/NX-OS beta-tester?)
