Hi,
I have been experimenting with conditional BGP default-originate route-maps. I
would like to advertise a default route if route “a” AND route “b” are
available. For some reason I am only able to configure a logical OR operation
with a basic route map:
access-list 1 permit 1.1.1.1
access-list 1 permit 2.2.2.2
!
route-map CHECK_ROUTE_A_AND_B
match ip address 1
match ip address 2
!
router bgp 64512
neighbor 5.5.5.5 default-originate route-map CHECK_ROUTE_A_AND_B
The IOS then converts the route-map to the following which is basically a
logical OR:
route-map CHECK_ROUTE_A_AND_B
match ip address 1 2
The only way I have managed to get a conditional BGP default-originate working
with a logical AND operation is the rather convoluted example below:
track 1 ip route 1.1.1.1 255.255.255.255 reachability
track 2 ip route 2.2.2.2 255.255.255.255 reachability
!
track 3 list boolean and
object 1
object 2
!
ip route 169.254.1.1 255.255.255.255 Null0 track 3
!
access-list 1 permit 169.254.1.1
!
route-map CHECK_ROUTE_A_AND_B permit 10
match ip address 1
Does anyone know how I can achieve the same thing with a basic route-map?
Many thanks
Paul
