tunnel-type ipv6

Configures the source IPv6 address with mask and tunnel type for the transport tunnel packets to be terminated.

Syntax

tunnel-type gre [ ipv6-src ipaddr mask ]

no tunnel-type gre [ ipv6-src ipaddr mask ]

Parameters

gre: Specifies the type of tunnel to be terminated.
ipv6-src ipaddr mask: Specifies the source IPv6 address and mask configured in hexadecimal between 0 and FFFF. Example: 202:304:606:708:90a:b0c:d0e:f11.; The upper 4 bytes and lower 8 bytes of the mask must be zero because only 32 bits out of 128 bits of IPv6 are supported. Example: 0000:0000:FFFF:FFFF:0000:0000:0000:0000.

Modes

Transport tunnel config mode

Usage Guidelines

This command is available only to users with the admin role.

If all the parameters match along with the chassis MAC, the transport header is removed and packets are subjected to further processing.

If the IP address is not provided, all packets matching the tunnel type or transport header type are configured for termination.

Validations for the command are as follows:

Tunnel type must be GRE.
Valid IP address and mask must be provided.
Only valid unicast IP addresses are supported. Multicast IP addresses are not supported.
Only one tunnel type per transport tunnel is allowed. The configured tunnel type must be removed before you configure a new tunnel type.
If the same command is run more than once, the second and subsequent instances are ignored and no error is reported.
If the no form of the command is run without the configuration, the command is ignored and no error is reported.

Examples

The following example configures the transport tunnel.

device(config-transport-tunnel)# tunnel-type gre ipv6-src 2233:304:606:708:90a:b0c:d0e:f11 

device(config)# show transport-tunnel tt1 

                  Name : tt1 
      Source-Ipv6-Addr : 2233:304:606:708:90a:b0c:d0e:f11 
      Source-Ipv6-Mask : 0000:0000:FFFF:FFFF:0000:0000:0000:000 
           Tunnel-Type : GRE 
         Ingress-Group : none 
  
device# show running-config transport-tunnel 
transport-tunnel tt1 
  tunnel-type gre ipv6-src 2233:304:606:708:90a:b0c:d0e:f11 0000:0000:FFFF:FFFF:0000:0000:0000:000
