A device that is not directly connected to its destination subnet forwards an IP directed broadcast in the same way it would forward unicast IP packets destined to a host on that subnet. When a directed broadcast packet reaches a device that is directly connected to its destination subnet, that packet is broadcast on the destination subnet. The destination address in the IP header of the packet is rewritten to the configured IP broadcast address for the subnet, and the packet is sent as a link-layer broadcast.

If directed broadcast is enabled for an interface, incoming IP packets whose addresses identify them as directed broadcasts intended for the subnet to which that interface is attached are broadcast on that subnet.

ICMP Redirect Disable

ICMP redirects are sent by a router to the sender of an IP packet when a packet is being routed sub-optimally. The ICMP redirect informs the sending host to forward subsequent packets to that same destination through a different gateway.

By default, an interface allows ICMP redirect messages.

Range: 12 through 60 seconds

Default: 12 seconds

The default hello interval is 1000 milliseconds, and it can be a time in the range 100 through 600000 milliseconds (10 minutes). The default hello tolerance is 12 seconds, and it can be a time in the range 12 through 600 seconds (10 minutes). To reduce outgoing control packets on a TLOC, it is recommended that on the tunnel interface you set the hello interval to 60000 milliseconds (10 minutes) and the hello tolerance to 600 seconds (10 minutes) and include the no track-transport disable regular checking of the DTLS connection between the edge device and the controller. For a tunnel connection between a edge device and any controller device, the tunnel uses the hello interval and tolerance times configured on the edge device. This choice is made to minimize the traffic sent over the tunnel, to allow for situations where the cost of a link is a function of the amount of traffic traversing the link. The hello interval and tolerance times are chosen separately for each tunnel between a edge device and a controller device. Another step taken to minimize the amount of control plane traffic is to not send or receive OMP control traffic over a cellular interface when other interfaces are available. This behavior is inherent in the software and is not configurable.

Enable this option to limit the remote TLOCs that the local TLOC can establish BFD sessions with. When a TLOC is marked as restricted, a TLOC on the local router establishes tunnel connections with a remote TLOC only if the remote TLOC has the same color.

Group

Enter a group number.

Range: 1 through 4294967295

Border

Enable this option to set the TLOC as a border TLOC.

Maximum Control Connections

Specify the maximum number of Cisco SD-WAN Controllers that the WAN tunnel interface can connect to. To have the tunnel establish no control connections, set the number to 0.

Range: 0 through 100

Default: 2

NAT Refresh Interval

Enter the interval between NAT refresh packets sent on a DTLS or TLS WAN transport connection.

Range: 1 through 60 seconds

Default: 5 seconds

Validator As Stun Server

Enable Session Traversal Utilities for NAT (STUN) to allow the tunnel interface to discover its public IP address and port number when the Cisco IOS XE Catalyst SD-WAN device is located behind a NAT.

Exclude Controller Group List

Set the identifiers of one or more Cisco SD-WAN Controller groups that this tunnel is not allowed to connect to.

Range: 1 through 100

Manager Connection Preference

Set the preference for using a tunnel interface to exchange control traffic with Cisco SD-WAN Manager.

Range: 0 through 8

Default: 5

Full Port Hop

Minimum release: Cisco IOS XE Catalyst SD-WAN Release 17.18.1a

Enable full port hopping at the TLOC level to allow devices to establish connections with controllers by switching to the next port if the current port is blocked or non-functional.

Default: Disabled

Port Hop

Enable port hopping. When a router is behind a NAT, port hopping rotates through a pool of preselected OMP port numbers (called base ports) to establish DTLS connections with other routers when a connection attempt is unsuccessful. The default base ports are 12346, 12366, 12386, 12406, and 12426. To modify the base ports, set a port offset value.

Default: Enabled

Starting from Cisco IOS XE Catalyst SD-WAN Release 17.18.1a, this field is deprecated. Instead use the Full Port Hop option. See the Full Port Hop field.

Low-Bandwidth Link

Enable this option to characterize the tunnel interface as a low-bandwidth link.

Tunnel TCP MSS

Specify the maximum segment size (MSS) of TPC SYN packets passing through the router. By default, the MSS is dynamically adjusted based on the interface or tunnel MTU such that TCP SYN packets are never fragmented.

Range: 500 to 1460 bytes

Default: None

Clear-Dont-Fragment

Enable this option to clear the Don't Fragment (DF) bit in the IPv4 packet header for packets being transmitted out the interface. When the DF bit is cleared, packets larger than the MTU of the interface are fragmented before being sent.

Network Broadcast

Enable this option to accept and respond to network-prefix-directed broadcasts.

Allow Service

Allow or disallow the following services on the interface:

• All

• BGP

• DHCP

• NTP

• SSH

• DNS

• ICMP

• HTTPS

• OSPF

• STUN

• SNMP

• NETCONF

• BFD

Encapsulation

GRE

Use GRE encapsulation on the tunnel interface. By default, GRE is disabled.

If you select both IPsec and GRE encapsulations, two TLOCs are created for the tunnel interface that have the same IP addresses and colors, but that differ by their encapsulation.

GRE Preference

Specify a preference value for directing traffic to the tunnel. A higher value is preferred over a lower value.

Range: 0 through 4294967295

Default: 0

GRE Weight

Enter a weight to use to balance traffic across multiple TLOCs. A higher value sends more traffic to the tunnel.

Range: 1 through 255

Default: 1

IPsec

Use IPsec encapsulation on the tunnel interface. By default, IPsec is enabled.

If you select both IPsec and GRE encapsulations, two TLOCs are created for the tunnel interface that have the same IP addresses and colors, but that differ by their encapsulation.

IPsec Preference

Specify a preference value for directing traffic to the tunnel. A higher value is preferred over a lower value.

Range: 0 through 4294967295

Default: 0

IPsec Weight

Enter a weight to use to balance traffic across multiple TLOCs. A higher value sends more traffic to the tunnel.

Range: 1 through 255

Default: 1

NAT

Enable this option to have the interface act as a NAT device.

UDP Timeout*

Specify when NAT translations over UDP sessions time out.

Range: 1 through 8947 minutes

Default: 1 minutes

TCP Timeout*

Specify when NAT translations over TCP sessions time out.

Range: 1 through 8947 minutes

Default: 60 minutes (1 hour)

IP Address*

Enter the IP address for the ARP entry in dotted decimal notation or as a fully qualified host name.

MAC Address*

Enter the MAC address in colon-separated hexadecimal notation.

MAC Address

Specify a MAC address to associate with the interface, in colon-separated hexadecimal notation.

IP MTU

Specify the maximum MTU size of packets on the interface.

Range: 576 through 9216

Default: 1500 bytes

Interface MTU

Enter the maximum transmission unit size for frames received and transmitted on the interface.

Range: 1500 through 9216

Default: 1500 bytes

TCP MSS

Specify the maximum segment size (MSS) of TPC SYN packets passing through the router. By default, the MSS is dynamically adjusted based on the interface or tunnel MTU such that TCP SYN packets are never fragmented.

Range: 500 to 1460 bytes

Default: None

TLOC Extension

Enter the name of a physical interface on the same router that connects to the WAN transport. This configuration then binds this service-side interface to the WAN transport. A second router at the same site that itself has no direct connection to the WAN (generally because the site has only a single WAN connection) and that connects to this service-side interface is then provided with a connection to the WAN.

Tracker

Tracking the interface status is useful when you enable NAT on a transport interface in VPN 0 to allow data traffic from the router to exit directly to the internet rather than having to first go to a router in a data center. In this situation, enabling NAT on the transport interface splits the TLOC between the local router and the data center into two, with one going to the remote router and the other going to the internet.

When you enable transport tunnel tracking, Cisco Catalyst SD-WAN periodically probes the path to the internet to determine whether it is up. If Cisco Catalyst SD-WAN detects that this path is down, it withdraws the route to the internet destination, and traffic destined to the internet is then routed through the data center router. When Cisco Catalyst SD-WAN detects that the path to the internet is again functioning, the route to the internet is reinstalled.

Enter the name of a tracker to track the status of transport interfaces that connect to the internet.

IP Directed-Broadcast

An IP directed broadcast is an IP packet whose destination address is a valid broadcast address for some IP subnet but which originates from a node that is not itself part of that destination subnet.

A device that is not directly connected to its destination subnet forwards an IP directed broadcast in the same way it would forward unicast IP packets destined to a host on that subnet. When a directed broadcast packet reaches a device that is directly connected to its destination subnet, that packet is broadcast on the destination subnet. The destination address in the IP header of the packet is rewritten to the configured IP broadcast address for the subnet, and the packet is sent as a link-layer broadcast.

If directed broadcast is enabled for an interface, incoming IP packets whose addresses identify them as directed broadcasts intended for the subnet to which that interface is attached are broadcast on that subnet.
