The LB VIP should be advertised by the Tier1 router only if it is on the external network. To do that, the global advertise vp flag will not be set, and instead a rule with a filter to advertise only the VIPs on the external network is added. In addition, an admin utility is added to update already existing routers with loadbalancers. Since VPNaaS also uses the router advertisement rules, its code was also updated so that each application will handle only its own rules. Change-Id: Ibfac0406a8c3009c323828cc42c96012e70cb0a9
