Topologia para brincar com Frame Relay! - Ponto-a-ponto

Segue uma topologia para brincar com Frame Relay!

Aqui usei dois PVCs ponto-a-ponto, emulando 3 roteadores 3745. O Roteador Campinas interliga Ubatuba e Trindade em circuitos diferentes (1:110 -> 2:101; 1:220 -> 3:202), sendo que cada um deles têm uma subrede diferente (192.168.XXX.0 /30, onde XXX reflete o número do DLCI de cada PVC na ponta do roteador Campinas).

Segue abaixo as configurações das interfaces:

• Campinas:

Campinas#show run interface serial1/0

Current configuration : 93 bytes
!
interface Serial1/0
 no ip address
 encapsulation frame-relay
 serial restart-delay 0
end

Campinas#

end

Campinas#
