Bom vou considerar este LAB num nivel de dificuldade maior, pois envolve ipv6.
A falha é até que simples, pensei neste LAB mais como uma introdução a IPV6.
Este LAB vai sem topologia para dificultar um pouco mais.
Sua tarefa estara completa quando:
1 - O Roteador R1 estiver pingando a Loopback (IPV6) do R3
2 - O Roteador R3 estiver pingando a Loopback (IPV6) do R1
R1#ping ipv6 101:0:0:3::3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 101:0:0:3::3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 96/143/192 ms
R3#ping ipv6 101:0:0:3::1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 101:0:0:3::1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 96/149/192 ms
