Dears,
As per solution guide I partially implemented R1 Configuration to check that no-export should be also propogated but it was not as per below..Can some one please check its a bug or I make some mistake.(Already have done clear ip route/clear bgp *) but no effect.

Implemented without Attribute MAP in order to check the no-export should be propogated to R6 but it is not
