The difference between a central services topology and a hub and spoke topology is that with the latter spokes can communicate with one another through the hub whereas with the former spokes can only communicate with the hub. My understanding is that hub and spoke works by having 2 routing adjacencies configured between the Hub CE and its PE, while the Central services topology is much simpler in that the hub (central services) CE only requires a single routing adjacency with its PE. hub router spoke router hub vrf vrf import null import hub export hub export spoke spoke vrf import spoke export null central services router client router vrf vrf import client import services export services import client What I am wondering is whether this is too simplistic a view of central services. In a central services configuration, when routes are imported into a VRF with RT1, and the VRF is set to export routes with RT2, is there anything to prevent imported routes from being automatically advertised (especially with Cisco IOS)? -- Chris Ullock IP Product Planner Syndesis ullock@syndesis.com ------- The MPLS-OPS Mailing List Subscribe/Unsubscribe: http://www.mplsrc.com/mplsops.shtml Archive: http://www.mplsrc.com/mpls-ops_archive.shtml |
