Subnetting eksempel

VLSM and CIDR

Classful IP Addressing

1
2

Classless IP addressing

3

Classless Routing Protocol

Classless routing protocols send the subnet mask in their updates.

Example of CIDR
  • RIPv2
  • OSPFv2
  • EIGRP
  • IS-IS
  • BGPv4

VLSM

VLSM in Action

5
  1. Netværket starter langsomt(de inderste 5 routere) og der kommer flere og flere enheder på; der bliver behov for flere subnets.
  2. De oprindelige /16 subnets bliver nu subnettet ned til mindre netværk.
6

CIDR

Route Summarization

7
CIDR er synonym med Supernetting
