6 To 4 Tunneling
Tunneling
패킷을 Incapsulation 하여 전달하는 것을 Tunneling이라한다. 캡슐화를 풀지 않는 이상 어떤 패킷이 전달되는지 다른 노드에서 알 수 없다.
6 To 4 Tunneling
IPv6는 IPv4의 IP 고갈에 의해서 등장했다. 따라서 IPv4로 이미 구축된 망이 있으며 IPv4와 통신이 불가능하지만 새로운 망인 IPv6의 망을 구축할 수 있다.
다만 IPv6끼리 통신이 가능하나 IPv6 - IPv4 -IPv6와 같이 서로 이어지지 않은 망 구조일때 IPv6와 IPv4를 혼용하는 경계라우터에서 다른 경계라우터로 Incapsulation하여 전달하는 방식을 사용 할 수 있다. 이를 6 to 4 Tunneling이라한다. cisco에서는 GRE라 한다.
현제까지 공부한 가상 인터페이스 종류
1. Loopback Interface
2. SVI : vlan 인터페이스 --> L2 인터페이스로 L3
3. VL0 --> OSPF : ABR 및 ABR끼리의 가상 경로 생성. Tunneling
4. Tunnel Interface : 가상 터널로 여러동작 모드가 있음.
명령어
** 터널링시 해당 라우터끼리는 Next Hop(Neighbor Node)로 인식

#주소값을 사용하지 않음을 선언.
#그러나 주소가 없을 경우 동작을 안하므로 다른 인터페이스의 주소를 끌어다 사용.
