Create a multiprotocol operational network using EIGRP, OSPF, and RIPv2 protocol.

The above network has RIPv2, OSPF, and EIGRP protocols in Intranet and is connected to two ISPs thru BGP protocol. As a consultant write a technical proposal to implement the following solutions.

1. Create a multiprotocol operational network using EIGRP, OSPF, and RIPv2 protocol.
2. Implement a secure update of OSPF and EIGRP protocol.
3. Implement virtual link in one segment of the network
4. Implement a redistribution solution
5. Implement BGP connection to ISPs

Implement a solution which avoids your network becoming a transit hub for BGP
