Requirment
In order to facilitate in keeping the global BGP tables as small as possible, your BGP routing policy dictates the Rouer5 should advertise one route representing your entire major network 132.1.0.0 to RB.
Since the Ethernet segment between R5 and RB in AS 264s only connection to your network, AS 264 does not need to have any longer matches than the summary route.
In order to assure optimal forwarding throughout your internal, insure that no other routers see this summary route,
Do not apply any access-list or prefix-list filtering towards AS 264.
Note: That R5 connect to R13 via Frame Relay then to rest of the network, and to R4 via ISDN and to the rest of the network
R5:
router bgp 300
aggregate-address 132.1.0.0 255.255.0.0 summary-only
neighbor 132.1.35.3 route-map ANY_OTHER out
neighbor 132.1.35.3 unsuppress-map THE_RESET
neighbor 132.1.45.4 route-map ANY_OTHER out
neighbor 132.1.45.4 unsuppress-map THE_RESET
!
ip prefix-list DENY_ANY_OTHER seq 5 permit 132.1.0.0/16
!
route-map ANY_OTHER deny 20
match ip address prefix-list ANY_OTHER
!
route-map ANY_OTHER permit 30
!
route-map THE_RESET permit 10
I get confused between "permit" keyword in prefix-list command and "deny" keyword in route-map statement, I feel there is contradiction
