The Area ID in OSPF is used to segment the network into areas, which helps in reducing routing table size and improving efficiency.

The default administrative distance of EIGRP is 90, which makes it more preferred than OSPF (which has an administrative distance of 110) when both protocols are present.

OSPF is generally considered more scalable than EIGRP, especially in larger networks, due to its hierarchical design and area segmentation.

EIGRP primarily uses bandwidth as its metric, but it also considers delay, load, and reliability to calculate the best path.

OSPF supports a hierarchical network topology, allowing for efficient routing and management of large networks through the use of areas.

EIGRP (Enhanced Interior Gateway Routing Protocol) is classified as a hybrid routing protocol because it combines features of both distance vector and link state protocols.

The command 'router eigrp [AS number]' is used to enter EIGRP configuration mode on a Cisco router.

OSPF (Open Shortest Path First) supports Variable Length Subnet Masking (VLSM) and Classless Inter-Domain Routing (CIDR), allowing for more efficient IP address usage.

EIGRP is a classless routing protocol, meaning it supports variable-length subnet masking (VLSM) and does not use classful routing.

OSPF uses the Dijkstra algorithm, also known as the Shortest Path First (SPF) algorithm, to calculate the shortest path to each node in the network.
