PAT ip advertisement via BGP

[mtechnology]

Can i advertise a natted IP through BGP

The scenario is

R1-----R2------R3

R2 and R3 are running BGP

R1 houses the subnet 10.10.10.0/24

R2 will pat these address to a public IP say 100.100.100.100

I want to advertise 100.100.100.100 via BGP

I have added a null0 route to 100.100.100.100 on R2 and advertised via BGP

Will this work ?

thanks in advance

Yes that will definitely work. or you can create a loopback and advertise that interface into BGP as well.
