ToDo

Grundkonfiguration af Router

  1. Slet tidligere konfigurationer. Se evtuelt artiklen Cisco basic configuration
R5# <input>erase startup</input>
R5# <input>reload</input>
  1. Kør setup programmet vælg cisco,class og cisco som passwords-

IPv4 overordnet

  1. Konfigurer IPv4 adresser på Fa0/0, Fa0/1, Looopback 0 konfigurer et kundenet på loopback 10
  2. Konfigurerer IPv4 IS-IS inden for de enkelte AS (Anvend loopback 0 til at finde NSAP adresse)
  3. Konfigurer IPv4 iBGP mellem routerne i AS'et
  4. 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
  5. Test at der er fuld IPv4 konnektivitet

IPv4 adresser på interfaces

interface Loopback0
 ip address 192.168.217.1 255.255.255.255
!
interface Loopback10
 description Kundenet der skan annonceres til alle
 ip address 192.168.218.1 255.255.255.255
!
interface FastEthernet0/0
 description Link to R6
 ip address 192.168.216.1 255.255.255.0
!
interface FastEthernet0/1
 description Link to R4
 no shutdown
 ip address 192.168.212.2 255.255.255.0

IPv4 IS-IS indenfor AS'et

iBGP indenfor AS'et

router bgp 300

 network 192.168.216.0 mask 255.255.255.0
 no auto-summary

eBGP til nabo-as

router bgp 300
 neighbor 192.168.212.1 remote-as 200
 neighbor 192.168.212.1 update-source FastEthernet0/1

IPv4 Test kommandoer

  • show cdp neighbors
  • show ip route
IS-IS
  • show isis neighbors
  • show isis database detail
BGP
  • show ip bgp neighbors
  • show ip bgp summary
  • show ip bgp



Vent på alle hold er færdig med IPv4

IPv6 overordnet

  1. Konfigurer IPv6 adresser på Fa0/0 og Fa0/1
  2. Konfigurer IPv6 IS-IS på fa0/0 og Fa0/1
  3. Konfigurer IPv6 iBGP til routere i AS'et
  4. Konfigurer IPv6 eBGP til nabo AS'et
    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 i address-family ipv6
  5. Test der er fuld IPv6 Konnektivitet

IPv6 adresser

interface loopback 0
 ipv6 address 2001:16d8:dd85:a501::1/128
!
interface loopback 10

IPv6 IS-IS
