For connect some customer we want to advertise only one network out and different networks in they provide us. For this I read about route-map and advertising-map feature in Cisco Docu.
For example this one for feature advertis-map:
router bgp 2 bgp log-neighbor-changes network 18.104.22.168 mask 255.255.255.0 neighbor 10.10.10.1 remote-as 1 neighbor 10.10.10.1 advertise-map ADVERTISE ! access-list 60 permit 22.214.171.124 0.0.0.255 ! route-map ADVERTISE permit 10 match ip address 60 !
And this one for the route-map feature:
router bgp 2 bgp log-neighbor-changes network 126.96.36.199 mask 255.255.255.0 neighbor 10.10.10.1 remote-as 1 neighbor 10.10.10.1 route-map RED out ! ip prefix-list 1 permit 188.8.131.52/24 ! route-map RED permit 10 match ip address prefix-list 1
I have found this booth Solutions to limit the number of networks that announced to customer. The goal is to Create a routing to a BGP Member and advertise only one subnet to the customer, the customer himself advertise one network in our direction? Is it possible with one of this solution and what is the diffrence between this solutions?
