Hi I'm new to MPLS but have a CCNA and understand the concepts of frame relay. My query is we are looking at putting in a 3 point MPLS circuit that connects our 3 offices, 2 of which are branch offices and the third is the headoffice. My queries are :
1. Can the Internet Access for the branch offices flow directly through the head office ?
2. Does the concept regarding subnetting remain the same as with frame relay, ISDN etc. i.e Head office subnet can be say 192.168.1.x and the branch offices can be 192.168.2.x and 192.168.3.x and the frame relay routers do the inter-routing between the sites ?
