Hi I am with a great problem. We are changing to several routers in our customer. The topology is, internal network <-> to balancer <-> old to router <-> MPLS <-> old router/new to router <-> to balancer <-> internal network destination. We already change router of the Central Site and all the branch offices had kept normal communication more, having access applicatory and all. However, when we change routers of the branch offices, it does not have conectividade. In all to router them of the branch offices 2 routes, one for the internal net and another one exist default for the MPLS. However, without balancer, it has conectividade. The administrator of balancer (linux), said that he does not have knotting for mac. But I am lost now, therefore he only has 2 routes in router, without balancer he has conectividade, with it up, does not have, with old to only router, that running-config ?copied? for new had its routers and the administrator of balancer says that has problems of routes in router. Somebody can give a light to me?
