Challenge 1

Multilayer Switch

Set up the VLAN database:

  • (config)#vlan 5 > users
  • (config)#vlan 6 > DC

Set up the interfaces for each vlan

  • (config)#int vlan 5 > ip address 172.16.5.1 255.255.255.0
  • (config)#int vlan 6 > ip address 172.16.6.1 255.255.255.0
  • (config)#int vlan 10 > ip address 172.16.10.2 255.255.255.0

Set up routing with ip route and configure OSPF:

  • (config)#router ospf 1
  • (config-router)#network 172.16.5.0 0.0.0.255 area 0
  • (config-router)#network 172.16.6.0 0.0.0.255 area 0
  • (config-router)#network 172.16.10.0 0.0.0.255 area 0

When I had trouble with this it was because I forgot to advertise ALL the networks directly attached to a router

BTV Router

Set up interfaces

  • (config)#int fa 0/0 > ip address 172.16.10.1 255.255.255.0
  • (config)#int fa 0/1 > ip address 192.168.2.2 255.255.255.252
  • (config)#int serial 0/1/0 > ip address 172.16.0.1 255.255.255.252

Turn them each on with no shut

Configure ospf

  • (config)#router ospf 1
  • (config-router)#network 172.16.10.0 0.0.0.255 area 0
  • (config-router)#network 172.16.0.0 0.0.0.3 area 0
  • (config-router)#network 172.16.2.0 0.0.0.3 area 0

MTL-Router

config interfaces

  • (config)#int se 0/1/0 > ip address 172.16.0.2 255.255.255.252
  • (config)#int fa0/0 > ip address 172.16.20.1 255.255.255.0

Turn them each on with no shut

Configure OSPF

  • `(config)#router ospf 1
  • (config-router)#network 172.16.0.0 0.0.0.3 area 0
  • (config-router)#network 172.16.20.0 0.0.0.255 area 0

Challenge 2

BTV Router

Set the default route on BTV router to the ISP:

  • (config) ip route 0.0.0.0 0.0.0.0 192.168.2.1

Send this default route to other routers in the area:

  • (config)#router ospf 1 > default-information originate

Set up BGP

  • (config)#router bgp 3033
  • (config-router)#neighbor 192.168.2.1 remote-as 1010
  • `(config-router)#redistribute ospf 1

Vermont ISP Router

Configure Interfaces:

  • int fa 0/0 > ip address 192.168.2.1 255.255.255.252
  • int fa 0/1 > ip address 192.168.1.1 255.255.255.252

Configure bgp:

  • (config)#router bgp 1010
  • (config-router)#neighbor 192.168.1.2 remote-as 2054
  • (config-router)#neighbor 192.168.2.2 remote-as 3033

Pacific ISP Router

Configure Interfaces

  • int fa 0/0 > ip address 192.168.1.2 255.255.255.252
  • int fa 0/1 > ip address 192.168.3.1 255.255.255.252
  • int se 0/1/0 > ip address 192.168.4.1 255.255.255.252

Configure BGP

  • (config)#router bgp 2054
  • (config-router)#neighbor 192.168.1.1 remote-as 1010
  • (config-router)#neighbor 192.168.4.2 remote-as 5132
  • (config-router)#neighbor 192.168.3.2 remote-as 34908

PARTNER Router

Configure Interfaces

  • int fa 0/0 > ip address 192.168.3.2 255.255.255.252
  • int fa 0/1 > ip address 10.15.6.1 255.255.255.0

Configure BGP

  • (config)#router bgp 34908
  • (config-router)#neighbor 192.168.3.1 remote-as 2054
  • (config-router)#network 10.15.6.0 mask 255.255.255.0

Configure the neighbor then advertise the other network connected to you

  • int fa 0/0 > ip address 10.200.24.1 255.255.255.0
  • int se 0/1/0 > ip address 192.168.4.2 255.255.255.252

Configure BGP

  • (config)#router bgp 5132
  • (config-router)#neighbor 192.168.4.1 remote-as 2054
  • (config-router)#network 10.200.24.0 mask 255.255.255.0
