Module 2: EIGRP
2.1 EIGRP Fundamentals and Features
- Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco-proprietary routing protocol. It has been described as a hybrid routing protocol, because it combines the best of distance vector routing protocols with link-state algorithms.

Info:
A virtual link is a link that allows discontiguous area 0s to be connected or a disconnected area to be connected to area 0 via a transit area. You should use the OSPF virtual link feature only in very specific cases, such as for temporary connections or backup after a failure. Virtual links should not be used as a primary backbone design feature and should be avoided if possible.
The area virtual-link command includes the router ID of the far-end router. To find the router ID in the far-end router, use the:<br>
show ip ospf
show ip ospf interface
show ip protocol
commands on that remote router, as illustrated in the Figure
