Domiciano,
 
Would it be possible for u to send a graphic of how u set them up and the configs of
the ASBRs and RR's if any. That would help to know how they were setup.
 
Aditya, when u say EBGP u are referring between ASBR's right ? and when u say
 MP-eBGP u are referring between RR's.
 
Could u clarify with a small text graphic so that it would be easy (sorry i am a visual
person)
 
Thanks,
 
Annu.

Annu,with EBGP family inet labeled-unicast you can *send* prefixes+labels 
as confirmed by Domiciano.
For MP-eBGP you need to enable family inet-vpn for VPN-v4 route distribution.


Domiciano,I assume you wld be advt PE /32 prefix+labels between the ASBR's.
On the juniper,was the prefix recvd from cisco getting installed in inet.3.
It would really help if you can send me the test results for the interop or 
just the output from below cmds.

Thanks
Aditya
