Configuring Tunnel Interfaces (SRC CLI)

You can configure tunnel interfaces to use the redirect server in deployments where a router running JunosE Software does not have a direct connection to the C Series Controller.

Before you configure a tunnel interface, configure the interface on the C Series Controller.

See Configuring Gigabit Ethernet Interfaces for IPv4 (SRC CLI)

Use the following configuration statements to configure tunnel interfaces at the [edit] hierarchy level:

To configure a tunnel interface on a C Series Controller:

1. From configuration mode, access the configuration statement that configures tunnel interfaces.
   [edit]user@host# edit interfaces name tunnel

   For example:

   [edit]user@host# edit interfaces ip-tunnel tunnel

    

2. Configure the type of tunnel.
   [edit interfaces ip-tunnel tunnel]user@host# set mode ipip

   or

   [edit interfaces ip-tunnel tunnel]user@host# set mode gre

   or

   [edit interfaces ip-tunnel tunnel]user@host# set mode sit
3. Specify the IP address of the remote end of the tunnel.
   [edit interfaces ip-tunnel tunnel]user@host# set destination destination

   For example:

   [edit interfaces ip-tunnel tunnel]user@host# set destination 192.0.2.20
4. (Optional) Specify an IP address that will not change for the local tunnel endpoint. It must be an address on another interface of this host.
   [edit interfaces ip-tunnel tunnel]user@host# set source source

   For example:

   [edit interfaces ip-tunnel tunnel]user@host# set source 192.20.10.5
5. (Optional) For a GRE tunnel, specify a key.
   [edit interfaces ip-tunnel tunnel]user@host# set key key

   For example:

   [edit interfaces ip-tunnel tunnel]user@host# set key 250
6. (Optional) Specify an existing physical interface on the C Series Controller.
   [edit interfaces ip-tunnel tunnel]user@host# set interface interface

   For example:

   [edit interfaces ip-tunnel tunnel]user@host# set interface eth0
7. (Optional) Specify the lifetime of tunneled packets.
   [edit interfaces ip-tunnel tunnel]user@host# set ttl ttl

   For example:

   [edit interfaces ip-tunnel tunnel]user@host# set ttl 110
8. Verify the configuration by running the show command. For example:

   [edit interfaces]
   user@host# show
   
   unit 0 {
    family { 
       inet6 { 
         address 192.2.0.10/24;
       }
     }
   }
   ip-tunnel {
     tunnel { 
         mode ipip;
         destination 192.0.2.20;
         source 192.20.10.5;
         interface eth0;
         ttl 110;
       }
   }
