Flashcards for Routing Protocols Overview

RIP - Type

Distance vector protocol.

RIP - Metric

Hop count (maximum of 15 hops).

RIP - Admin Distance

RIP - Convergence

Slow.

RIP - Use Case

Small networks

EIGRP - Type

Advanced distance vector protocol (Cisco proprietary).

EIGRP - Metric

Bandwidth and delay.

EIGRP - Admin Distance

90 (internal)

EIGRP - Convergence

Very fast.

EIGRP - Use Case

Medium to large networks.

OSPF - Type

Link-state protocol.

OSPF - Metric

Cost (based on bandwidth).

OSPF - Admin Distance

OSPF - Convergence

Fast.

OSPF - Use Case

Large networks

IS-IS - Type

Link-state protocol.

IS-IS - Metric

Cost.

IS-IS - Admin Distance

IS-IS - Convergence

Fast.

IS-IS - Use Case

Large networks

BGP - Type

Path vector protocol.

BGP - Metric

Multiple attributes (e.g.

BGP - Admin Distance

20 (external)

BGP - Convergence

Average.

BGP - Use Case

Used between different autonomous systems (AS) on the internet.

Metric - Definition

A value used by routing protocols to determine the best path.

Admin Distance - Definition

A value that indicates the trustworthiness of a routing protocol (lower is better).
