in principle it would be enough NOT to configure redistribution between BGP and IGP (which is never the best idea). IP routing protocols are like "ships in the night" - they don´t see each otherunless you configure redistribution.
In addition I would apply the proper inbound and outbound filters to be sure an ISP failure/error will not get you in trouble. An example configuration could look like this:
description to ISP
ip address 184.108.40.206 255.255.255.252
router bgp 65000
network 220.127.116.11 mask 255.255.0.0
neighbor 18.104.22.168 remote-as 1 !replace with ISP AS
neighbor 22.214.171.124 prefix-list NoTrash in
neighbor 126.96.36.199 filter-list 1 out
neighbor 188.8.131.52 maximum-prefix 300000
ip as-path access-list 1 permit ^$
ip prefix-list NoTrash deny 192.168.0.0/16 le 32
ip prefix-list NoTrash deny 172.16.0.0/12 le 32
ip prefix-list NoTrash deny 10.0.0.0/8 le 32
ip prefix-list NoTrash deny 184.108.40.206/16 le 32
ip prefix-list NoTrash permit 0.0.0.0/0 le 24
ip route 220.127.116.11 255.255.0.0 Null 0 250
This assumes you want to announce 18.104.22.168/16 to the ISP as your official IP addresses. You need of course to adjust interfaces, IP addresses ans AS numbers.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
