Lab 8. IPv6 Tunnel GRE IP


Hapus terlebih dahulu konfigurasi tunnel mode ipv6 ip pada interface tunnel R1 dan R2 karena by default interface tunnel jika tidak di define manual, maka tunnel modenya adalah GRE.

R1:
R1(config)#int tunnel 0
R1(config-if)#no tunnel mode ipv6ip
R1(config-if)#exit

R3:
R3(config)#int tunnel 0
R3(config-if)#no tunnel mode ipv6ip
R3(config-if)#exit

Cek apakah sudah berubah menjadi GRE.

R1:
R1(config)#do show interface tunnel0 | i protocol
Tunnel0 is up, line protocol is up
  Tunnel protocol/transport GRE/IP
    0 unknown protocol drops

R3:
R3(config)#do show int tunnel0 | i protocol
Tunnel0 is up, line protocol is up
  Tunnel protocol/transport GRE/IP
    0 unknown protocol drops

Kita coba ping.

R1:
R1(config)#do ping 3::3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3::3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/27/40 ms
