Hello, 1- Is the 2 attributs in MBGP are additional attributes in the update message of a BGP update message or it is just another type of update messages. If it is not a new message, and those are just two additionnal attributes then what should be the meaning of the unfeasible routes field and also the NLRI field in the update message? There is nothing in the standards and specifications clarifying this point. 2- in the case where MBGP used for Multicast, is it the role of this protocol that just providing a new multicast topology or there is anything else?? because if a new topology isnt created with the MBGP then there is no meaning of this protocol. 3- in the multicast topology , how can the paths can be aggregated??? in the same manner of unicast ??? suppressing the unfeasible routes or how? thanx
