GRE-Tunnel. Ein GRE-Tunnel ist eine logische Schnittstelle auf einem Cisco Router, die eine Möglichkeit bietet, Passagierpakete innerhalb eines Transportprotokolls zu kapseln. Es handelt sich um eine Architektur, die entwickelt wurde, um die Services bereitzustellen und ein Punkt-zu-Punkt-Kapselungsschema zu implementieren GRE Tunnels with Tunnel Protection. In Cisco IOS Software Releases 15.4 (3)M/15.4 (3)S and later, the GRE tunnel line protocol state will follow the IPsec Security Association (SA) state, so the line protocol will remain down until the IPsec session is fully established Das Generic Routing Encapsulation ist ein Netzprotokoll, welches dazu dient, andere Protokolle einzukapseln und so in Form eines Tunnels über das Internet Protocol zu transportieren. GRE wurde von Cisco Systems entwickelt und 1994 erstmals im RFC 1701 standardisiert. 2000 wurde der RFC 1701 durch RFC 2784 abgelöst und im RFC 2890 erweitert. GRE setzt - wie UDP und TCP - direkt auf IP auf und verwendet die IP-Protokoll-Nummer 47. Beispiele für GRE-Anwendungen: VPN. GRE is developed by Cisco System. In order to configure the GRE tunnel, you must need connectivity between two remote routers through static Public IP address. So, let's configure the GRE Tunnel. GRE usages IP protocol number 47. By default, GRE does not perform any kind of encryption. Although, you can configure the GRE Tunnel over the IPSec.

Ich durfte mich jetzt etwas mit GRE Tunneln beschäftigen und mit dem Keepalive Mechanismus der darin steckt. GRE Tunnel sind erstmal nichts besonderes, sie tunneln in IP durch ein Netz in dem sich Quelle und Ziel erreichen können, ohne Verschlüsselung. Wenn man sie verschlüsseln möchte muss man zusätzlich IPSec machen, war bei mir aber nicht GRE Tunnel Keepalives weiterlese If tunnel mode gre ip is the default tunnel mode for tunnel interfaces, it may be omitted in the output of show running-config If the tunnel doesn't come up, one of the common reasons is, that the configured tunnel destination address is not reachable (for example because of a missing route). One of the most common reasons for flapping tunnel interfaces is recursive routing. Cisco called it Overlay Tunnel Virtualization (OTV). Other vendors referred to it as Next-Generation GRE or NVGRE. While OTV was successful, NVGRE had limited adoption, mainly because it came late to Network Virtualization and at the same time as the next generation protocol, Virtual Extensible LAN (VXLAN), was already making inroads

GRE tunnel on Cisco ASR 920. Close. 3. Posted by 1 year ago. Archived. GRE tunnel on Cisco ASR 920. Hey all, anyone of you having experience with Cisco ASR 920?
