how do you envision to find out the node originating a prefix in case of
inter-area prefixe?
[Pushpasis] The ABR on the originating area/level should be able to detect the
anomaly like other nodes in the same area/level and block re-advertisement.
Node N1 in area 1 advertises prefix P1 with SID X. ABR1 advertises P1 to
area 0.
Node N2 in area 2 advertises prefix P2 with SID X, ABR2 advertises P2 to
area 0.
Node 3 in area 0 get these two prefixes P1 and P2 from two different
ABRs. How does it know that the originators for P1 and P2 are different?
Do you expect the ABR1 and ABR2 to detect the collision and withdraw SID
advertisement to area 0? If yes, that may become source of all sorts of
problems.
thanks,
Peter
