Hi
I've got a problem to find a solution in resctricting NAT announce into BGP.
Here is my schema : Client router - Operator router (PE) - My edge router (CE) - other routers behind the CE
I'm doing a NAT on my CE. ip nat inside source static 10.10.32.0 192.168.0.0
10.10.32.0 is my local network that is announced to my CE in BGP.
192.168.0.0 is the NATted network in my CE ( for PE side).
I'm doing BGP with my PE. That is why i've : ip route 192.168.0.0 Null0 and a redistribution of my static route into BGP
Do to some specific architecture that i will not explain I'm trying to get dynamic announce from CE to the PE of the NAT network.
I mean if my CE don't receive 10.10.32.0 I don't want to announce to my PE 192.168.0.0
Can someone explain to me the way to do it if there is one.
Solved! Go to Solution.

BGP condiitional advertising can be the right tool to achieve this
