IP prefix list

[grapevine]

Suppose I create a prefix list and I didnot add the commands in red, what would happen? Will the redistribution happen at all?

router bgp 65100
no synchronization
bgp router-id 2.2.2.2
bgp log-neighbor-changes
redistribute ospf 1 route-map OSPF->BGP
neighbor 172.16.23.3 remote-as 65100
no auto-summary
!
ip access-list extended OSPF_Redist
deny ip host 10.0.0.0 host 255.255.255.0
permit ip any any
!
route-map OSPF->BGP permit 10
match ip address OSPF_Redist

Even though there is nothing manually configured in the ACL there is still an implicit deny set once the ACL is created, i would think without testing this it would block everything as its not configured to allow anything and the implicit still exists

Your telling it to redistribute ospf to bgp but then only on the condition of the ACL which would will only have an implicit deny statement when the RED config is not configured
