Configure GRE on NE20E

Publication Date:  2016-02-24 Views:  247 Downloads:  0
Issue Description

In order to establish a GRE tunnel on NE20E 172.17.33.82 to NE20E-S8 172.17.33.170 (and the reverse path as well) as shown in the picture .



Handling Process

We use static routes  to have reachability from the node with loopback 172.17.33.82 to 172.17.33.170 and the other way around.

 

 

 

 

The tunnel configuration is the following on both routers:

Router 172.17.33.170

 

 

 

Router 172.17.33.82

 

 

 

Tunnels don’t come up:

 

Router 172.17.33.82

 

 

 

Router 172.17.33.170

 

 

 

 

Solution

You need to configure tunnel interface starting with the number from target board.

 

 

For our configuration, target-board is 9 and the tunnel interface should be 9/ 0/100.
