Stefan,
Before you enabled the maximum-path command were you
able to successfully do this ping and trace?
Also, you said there is an IGP in AS2. Is this route
known only to BGP or have you redistributed it to the
IGP at R1 and R5. The TTL exceeded messages make me
think there's a routing loop here.
