Grundkonfiguration af Router

Slet tidligere konfigurationer. Se evtuelt artiklen Cisco basic configuration

Kør setup programmet vælg cisco,class og cisco som passwords-

IPv4 overordnet

Konfigurer IPv4 adresser på Fa0/0, Fa0/1, Looopback 0 konfigurer et kundenet på loopback 10
Konfigurerer IPv4 IS-IS inden for de enkelte AS (Anvend loopback 0 til at finde NSAP adresse)
Konfigurer IPv4 iBGP mellem routerne i AS'et
Konfigurer IPv4 eBGP til nabo AS
1. R1 og R8 skal konfigurere default-gateway til L3 switch
2. R1 og R8 konfigurerer default gateway til Lag 3 switch med BGP kommandoen default-information originate og annoncere network 0.0.0.0 i BGP
Test at der er fuld IPv4 konnektivitet

IPv6 overordnet

Konfigurer IPv6 adresser på Fa0/0 og Fa0/1
Konfigurer IPv6 IS-IS på fa0/0 og Fa0/1
Konfigurer IPv6 iBGP til routere i AS'et
Konfigurer IPv6 eBGP til nabo AS'et
