Study Notes
Routing Protocols
- Routing protocols are sets of rules used by routers to determine the best path for
- Enable routers to communicate with each other.
- Allow routers to share information about the network topology.
- Enable dynamic adjustments to routing tables based on current network conditions.
Interior Gateway Protocols (IGPs)
-
Link-State Protocols
- OSPF (Open Shortest Path First) is a link-state routing protocol used for medium to large networks.
- IS-IS (Intermediate System to Intermediate System) is a link-state protocol similar to OSPF but more often used in large ISP networks.
-
Distance-Vector Protocols
- RIP (Routing Information Protocol) is a distance-vector protocol utilizing hop count as a routing metric, best suited for small networks.
- IGRP (Interior Gateway Routing Protocol) is a distance-vector protocol, predecessor to EIGRP (Cisco proprietary), less common, largely replaced by EIGRP
-
Hybrid Protocols
- EIGRP (Enhanced Interior Gateway Routing Protocol) is a Cisco proprietary hybrid protocol that combines distance-vector and link-state features. More efficient than RIP and suitable for large networks.
Exterior Gateway Protocols (EGPs)
-
Path Vector Protocols
- BGP (Border Gateway Protocol) is the backbone protocol of the internet, primarily used for routing between different autonomous systems.
Specific Protocol Details
-
RIP (Routing Information Protocol)
- A distance-vector protocol utilizing hop count as a routing metric.
- Maximum of 15 hops.
- Suitable for small networks.
- Routing updates transmitted every 30 seconds.
-
OSPF (Open Shortest Path First)
- Link-state protocol using Dijkstra’s algorithm for shortest path calculation.
- Implemented in both IPv4 (OSPFv2) and IPv6 (OSPFv3) versions.
- Uses various metrics including dependability, bandwidth, latency, load, and MTU for optimal routing.
-
EIGRP (Enhanced Interior Gateway Routing Protocol)
- Hybrid protocol combining distance-vector and link-state features for efficient routing on large networks.
-
IS-IS (Intermediate System to Intermediate System)
- Link-state protocol, similar to OSPF but primarily used in large ISP networks.
-
BGP (Border Gateway Protocol)
- Path-vector protocol responsible for internet routing across autonomous systems.
