Without an address, you get an error: The receiving router de-encapsulates and forwards the original passenger protocol packets. Subnet used between BEast and Eastv6. Some examples of IP tunnels are;. They know what it is for, but sometimes just pick not to use a specific one. BNorth config do ping The GRE tunnel interface on the other side, where keepalives are not configured, remains up even if the other side of the tunnel is down.

That completes the tunnel and IPSec configuration. Without an address, you get an error: IPV6 is not enabled on this interface Rene. Even if the normal egress interface were to go down, traffic across the tunnel could continue to flow, if there is a route to the tunnel destination in the routing table.
The problem with the configuration of keepalives only on one side of the tunnel is that only the router that has keepalives configured marks its tunnel interface as down if the keepalive timer expires.
Rene, I tried using the following lab without configuring a global IPv6 address but it tunnelihg not work until I configured the global IPv6 address. Regardless of the number of network hops between the source and destination, the traffic passing over the tunnel sees it as a single hop. I only need two routers to demonstrate this.

The GRE tunnel interface on the other side, where keepalives are not configured, remains up even if the other side of the tunnel is down. Subnet used between BEast and Eastv6. Basically it means that we encapsulate IPv6 packets into IPv4 packets or the other way around so that it can be routed.
October 26, at 7: The payload is first encapsulated in a GRE packet. This lab is organized as follow: East site Internal network. Full Access to our Lessons. Router config-if tunnel destination?
They know what it is for, but sometimes just pick not to use a specific one. This process allows the routers in the network to forward traffic that might not be natively supported by the intervening routers.
Three routers are running IPv4. Full Access to our Lessons. Whether at you it is possible to put the ipv 6 tunnel on, if this way very much I asked it.
IPv6 over IPv4 GRE with IPSec |
North site Internal network. We can take a look there…. The GRE tunnel keepalive mechanism gives the ability for one side to originate and receive keepalive packets to and from a remote router even if the remote router does not support GRE keepalives.
The city of Dubai is a hub not only for tourists and oil companies but it is also popular amongst job seekers. BEast config do ping With the above three reasons for tunnel shut down are problems local to the router at the tunnel endpoints and do not lpv4 problems in the intervening network. But, it gives us an easy to remember IPv6 address that we can use to quickly test our tunnel. This is how we configure a tunnel interface. Explained As Simple As Possible.
