Packets: Sends a set number of packets (default: 1024) through one tunnel before switching to the next flowlet. This cycle repeats continuously to balance the network load.

Packet gap: Switches tunnels based on the time interval between packets. If the time gap between bursts exceeds the maximum latency difference among tunnels, a new flowlet is sent on a different tunnel.

This helps distribute traffic more effectively during natural pauses in data transmission.

Dynamically defines the group of tunnels used in a PPL network.

All tunnels: All available tunnels become part of PPL network.

Latency offset: Includes only those tunnels whose latency is within a configurable threshold of the lowest-latency tunnel.

Adaptive cluster: Groups tunnels dynamically into clusters based on real-time loss and latency measurements. Tunnels with similar loss (primary factor) and latency (secondary factor) are grouped together for packet distribution.

Enables packet reordering at the receiving end to reduce out-of-order delivery. If you disable this option, ensure that your application can independently handle packet reordering.

Rekey Time (seconds)

Specify how often a device changes the AES key. Before Cisco IOS XE Catalyst SD-WAN devices and Cisco vEdge devices can exchange data traffic, they set up a secure authenticated communications channel between them. The routers use IPSec tunnels between them as the channel, and the AES-256 cipher to perform encryption. Each router generates a new AES key for its data path periodically.

Range: 10 through 63113904 seconds (730 days)

Default: 86400 seconds (24 hours)

For the key to work, you must mark it as trusted in the Trusted Key field under Authentication.

Set NTP version*

Enter the version number of the NTP protocol software.

Range: 1 to 4

Default: 4

Set interface to use to reach NTP server

Enter the name of a specific interface to use for outgoing NTP packets. The interface must be located in the same VPN as the NTP server. If it is not, the configuration is ignored.

Prefer this NTP server*

Enable this option if multiple NTP servers are at the same stratum level and you want one to be preferred. For servers at different stratum levels, Cisco Catalyst SD-WAN chooses the one at the highest stratum level.

Add Authentication Keys

Key Id*

Enter an MD5 authentication key ID.

Range: 1 to 65535

MD5 Value*

Enter an MD5 authentication key. Enter either a cleartext key or an AES-encrypted key.

Trusted Key

Enter the MD5 authentication key to designate the key as trustworthy. To associate this key with a server, enter the same value that you entered for the Set authentication key for the server field under Server.

Authoritative NTP Server

Choose Global from the drop-down list, and enable this option if you want to configure one or more supported routers as a primary NTP router.

Stratum

Enter the stratum value for the primary NTP router. The stratum value defines the hierarchical distance of the router from its reference clock.

Valid values: Integers 1 to 15. If you do not enter a value, the system uses the router internal clock default stratum value, which is 8.

Source Interface

Enter the name of the exit interface for NTP communication. If configured, the system sends NTP traffic to this interface.

For example, enter GigabitEthernet1 or Loopback0.

Graceful Restart Enable

Enable graceful restart. By default, the graceful restart for OMP is enabled.

Paths Advertised Per Prefix

Specify the maximum number of equal-cost routes to advertise per prefix. A Cisco IOS XE Catalyst SD-WAN device advertises routes to Cisco Catalyst SD-WAN Controllers, and the controllers redistribute the learned routes, advertising each route-TLOC tuple. A Cisco IOS XE Catalyst SD-WAN device can have up to four TLOCs, and by default advertises each route-TLOC tuple to the Cisco Catalyst SD-WAN Controller. If a local site has two Cisco IOS XE Catalyst SD-WAN devices, a Cisco Catalyst SD-WAN Controller could potentially learn eight route-TLOC tuples for the same route. If the configured limit is lower than the number of route-TLOC tuples, the best route or routes are advertised.

Range: 1 through 16

Default: 4

BGP AS Path Auto-Translation

Enables automatic translation of the BGP as path length into the OMP preference value for BGP-learned routes. When this option is enabled, routes with shorter BGP aspaths are assigned a higher OMP preference. Specifically, the OMP preference for a BGP-learned route starts at 255 and is decremented by 1 for each AS in the BGP aspath. As a result, routes with fewer AS hops receive a higher preference within OMP route selection.

ECMP Limit

Specify the maximum number of OMP paths received from the Cisco Catalyst SD-WAN Controller that can be installed in the local route table of the Cisco IOS XE Catalyst SD-WAN device. By default, a Cisco IOS XE Catalyst SD-WAN device installs a maximum of four unique OMP paths into its route table.

Range: 1 through 16

Default: 4

Advertisement Interval (In Second)

Specify the time between OMP update packets.

Range: 0 through 65535 seconds

Default: 1 second

We recommend you to configure 5 seconds on edge devices and 20 seconds on vSmart.

Hold Time(In Second)

Specify how long to wait before closing the OMP connection to a peer. If the peer doesn’t receive three consecutive keepalive messages within the hold time, the OMP connection to the peer is closed.

Range: 0 through 65535 seconds

Defaults, by Cisco Catalyst SD-WAN Control Components release:

• 20.18.x and later: 300 seconds

• 20.16.x: 5400 seconds

• 20.12.1 to 20.15.x: 300 seconds

• Before 20.12.1: 60 seconds

Defaults, by Cisco IOS XE Catalyst SD-WAN release:

• 17.18.1 and later: 300 seconds

• 17.16.x: 5400 seconds

EOR Timer(In Second)

Specify how long to wait after an OMP session has gone down and then come back up to send an end-of-RIB (EOR) marker. After this marker is sent, any routes that weren’t refreshed after the OMP session came back up are considered to be stale and are deleted from the route table.

Range: 1 through 3600 seconds (1 hour)

Default: 300 seconds (5 minutes)

Overlay AS

Specify a BGP AS number that OMP advertises to the BGP neighbors of the router.

Shutdown

Enable this option to disable OMP and disable the Cisco Catalyst SD-WAN overlay network. OMP is enabled by default.

OMP Admin Distance Ipv4

To advertise a route over OMP, configure the OMP administrative distance for the IPv4 address lower than the leaked route administrative distance.

Range: 1 through 255

OMP Admin Distance Ipv6

To advertise a route over OMP, configure the OMP administrative distance for the IPv6 address lower than the leaked route administrative distance.

Range: 1 through 255

Graceful Restart(In Second)

Specify how often the OMP information cache is flushed and refreshed. A timer value of 0 disables OMP graceful restart.

Range: 0 through 604800 seconds (168 hours, or 7 days)

Default: 43200 seconds (12 hours)

Treat Hierarchical and Direct Paths Equally

(Minimum supported release: Cisco Catalyst SD-WAN Manager Release 20.13.1)

In a Multi-Region Fabric scenario, if using secondary regions, enable this option to enable packets to use all available paths rather than only direct paths.

By default, when a direct path is available to reach a destination, the overlay management protocol (OMP) enables only the direct path to the routing forwarding layer because the direct path uses fewer hops. This logic is part of route optimization. The result is that the forwarding layer, which includes application-aware routing policy, can only use the direct path.

Treat Hierarchical and Direct Paths Equally disables this comparison of the number of hops so that traffic can use either the direct secondary-region path (fewer hops) or the primary-region path (more hops). When you disable the comparison of the number of hops, OMP applies equal-cost multi-path routing (ECMP) to all routes, and packets can use all available paths.

Transport Gateway Path Behavior

(Minimum supported release: Cisco Catalyst SD-WAN Manager Release 20.13.1)

Choose one of the following:

• Prefer Transport Gateway Path: For devices that can connect through a transport gateway, use only the transport gateway paths, even if other paths are available.

• Do ECMP Between Direct and Transport Gateway Paths: For devices that can connect through a transport gateway and through direct paths, apply ECMP to all available paths.

Site Type
