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.

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


            
               interfaces  name  tunnel
                  {
               
               mode (ipip | gre | sit);
               destination  destination ;
               
               source  source; 
               
               key  key ;
               
               interface  interface ;
               
               ttl  ttl ;
               
               }
               interfaces  name  unit  unit-number  family inet {
               
               address  address ;
               
               }

To configure a tunnel interface on a C Series Controller:

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

Configure the type of tunnel.


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


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


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

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

(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

(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

(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

(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

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;
    }
}
