Packet Tracer Project
![- Configured the IP address scheme shown in the figure on each node.
- Configured OSPF & IS-IS as an IGP protocol in the core network and consider all nodes in the same
area.
- Configured the MPLS over the core trunks.
- Used the LDP as the label distributor.
- Configured iBGP relationships in the core network using the route reflector scheme show.
- Configured eBGP relationships between the following upstream providers peers.
- The main download path for the “Enterprise” which is summarized to [217.139.0.0/16 and 41.187.0.0/16] is through 1st SP and the backup path is through 2nd SP.
- The main download path for the “Broadband” 2nd SP and the backup path is through 1st SP.
- Both 1st and 2nd SP are only advertising the default route to AS 2092.
- The Main path of Upload traffic is through 1st SP and the backup through 2nd.
- Five customers have contracted with the ISP to connect their sites as the scheme (MPLS MPBGP(L3 VPN) - EIGRP - OSPF(Super Backbone) - RIP - MPLS L2 VP](https://cdn5.f-cdn.com/files/download/126440909/ISP.png?fit=crop&image-optimizer=force&format=webply&width=894&height=672)

Mahmoud is the correct choice to work with if you need someone experienced in Networking, BGP etc. He setup our additional upstreams/IX for our Juniper MX960 in no time while i could sit back and focus on our daily business. Reliable guy. Recommended!
