I have been tasked by a client to redesign their IP network. Their current network is comprised of:
Many Frame Relay WAN Circuits that have many spokes and two hubs. The two hubs are their Headquarters and Disaster Recovery sites.
3 MPLS WAN connections.
Their are several LANs located at the Headquarters and at the Disaster Recovery Site.
There are several Routing protocols currently in use including BGP towards the Internet and MPLS circuits, EIGRP on inside networks, some RIP, and some static.
The current IP addressing is what I would call "Hodge Podge". For example, at the headquarters, there are several LAN's that are in the 192.168.X.0/24 IANA range. Then at the Disaster Recovery Site there are some 172.16.X.X/24 networks.
I wanted to get a larger perspective from some of you whom have designed networks in the best... I am interested in Best Practices, and would also like to know if there is any recommeded documentation available that would assist in my readdressing scheme.
Thanks for any advice available
