Adam,
I believe you can achieve that by reverse logic:
!
access-list 1 address1
access-list 1 address2
access-list 1 address3
!
access-list 2 address4
access-list 2 address5
access-list 2 address6
!
route-map advertise1 permit 10
match ip address 1
!
route-map advertise1 permit 20
!
route-map advertise2 permit 10
match ip address 2
!
route-map advertise2 permit 20
!
neighbor 1.1.1.1 advertise-map advertise2 exist-map advertise1
!
Do not forget that, you have to read the last statement backward...ie
whenever route-map 'advertise1' return a TRUE match, then advertise, the
routes represented by route-map 'advertise2'. Route-map 'advertise1' will
alway return a true value as long as one of the conditions it is monitoring
it true.
