RFC 2328 is supported by default on Dell EMC Networking OS and it is indicated in the show ip ospf command output.

OSPF ACK Packing
The OSPF ACK packing feature bundles multiple LS acknowledgements in a single packet, significantly reducing the number of
ACK packets transmitted when the number of LSAs increases.
This feature also enhances network utilization and reduces the number of small ACK packets sent to a neighboring router. OSPF
ACK packing is enabled by default and non-configurable.
Setting OSPF Adjacency with Cisco Routers
To establish an OSPF adjacency between Dell EMC Networking and Cisco routers, the hello interval and dead interval must be
the same on both routers.
In Dell EMC Networking OS, the OSPF dead interval value is, by default, set to 40 seconds, and is independent of the OSPF
hello interval. Configuring a hello interval does not change the dead interval in Dell EMC Networking OS. In contrast, the OSPF
dead interval on a Cisco router is, by default, four times as long as the hello interval. Changing the hello interval on the Cisco
router automatically changes the dead interval.
To ensure equal intervals between the routers, use the following command.
● Manually set the dead interval of the Dell EMC Networking router to match the Cisco configuration.
INTERFACE mode
ip ospf dead-interval <x>
In the following example, the dead interval is set at 4x the hello interval (shown in bold).
In the following example, the dead interval is set at 4x the hello interval (shown in bold).
Configuration Information
The interfaces must be in Layer 3 mode (assigned an IP address) and enabled so that they can send and receive traffic. The
OSPF process must know about these interfaces.
To make the OSPF process aware of these interfaces, they must be assigned to OSPF areas.
You must configure OSPF GLOBALLY on the system in CONFIGURATION mode.
NOTE: Loop back routes are not installed in the Route Table Manager (RTM) as non-active routes.
OSPF features and functions are assigned to each router using the CONFIG-INTERFACE commands for each interface.
NOTE: By default, OSPF is disabled.
Configuration Task List for OSPFv2 (OSPF for IPv4)
You can perform the following tasks to configure Open Shortest Path First version 2 (OSPF for IPv4) on the switch. Two of the
tasks are mandatory; others are optional.
The following configuration tasks include two mandatory tasks and several optional tasks:
● Enabling OSPFv2 (mandatory)
● Assigning a Router ID
