Thank you very much. What I want is like this: R1 and R2 in NSSA, R1 is ABR, R2
is ASBR and redistribute in one route like connect(which is not in the ospf ar
ea). I hope to let the connected route on R2 can't be seen out of the NSSA. I t
ried the 'summary-address x.x.x.0 255.255.255.0 no-advertise' on R2, it just le
ts the Lsa7 disappeared. When I use 'area y nssa no-distri' (Vincent's suggesti
on) on R2, it have the same effect. Is this a bug too? What can I do to achieve
this on R1 or R2?
And forwarding address is 0.0.0.0, what's that mean? Follow a last sort route?
Good luck for the number, I have 9 days to go, can't breathe when thinking abou
t it
Zeng
