Only accept/announce RFC 1918 IPs on BGP peering? Routing policy?

Hi, We are using Juniper as PE router and Cisco as CE router. The issue is that I'm able to see the routes on PE(Juniper) and from "advertising-protocol bgp" output able to see that prefixes (ex 222.1.1.x) is being advertised but when I check on CE router.. there is noting related to 222.1.1.x and seeing routes related only to RFC 1918 (10.x.x.x, 172.x.x.x, 192.168.x.x).

We are not using any filtering on CE and as far as I can see on PE there is no much filtering applied on the peering.

Is there any way that global policy is kicks in somewhere(PE or CE)? and does the output from "advertising-protocol bgp" is actually being prefixes advertised to it peer(CE)?
