9. 1.In computer networking, the default route is a setting on a computer defining the packet
forwarding rule to use when no specific route can be determined for a given Internet Protocol
(IP) destination address. All packets for destinations not established in the routing table are
sent via the default route.

11. 1.EIGRP (Enhanced Interior Gateway Routing Protocol) is a network protocol that lets
routers exchange information more efficiently than with earlier network protocols. EIGRP is a
Cisco-proprietary routing protocol for TCP/IP. It's actually based on Cisco's
proprietary IGRP routing protocol, with many enhancements built into it. Because it
has its roots in IGRP, the configuration is similar to IGRP; however, it has many link
state characteristics that were added to it to allow EIGRP to scale to enterprise
network sizes. To know these characteristics read our previous article.
12. 1.Open Shortest Path First (OSPF) is a routing protocol for Internet Protocol (IP) networks. It
uses a link state routing algorithm and falls into the group of interior routing protocols,
operating within a single autonomous system (AS).
