OSPFv2 Domain Settings dialog box

Use this dialog box to create an OSPFv2 Domain Settings element.

For information about Free Range Routing (FRR) syntax, see https://⁠docs.frrouting.org/en/latest/.

Option	Definition
Name	The name of the element.
ABR Type	Set the value for `ospf abr-type`. If an area border router (ABR) does not have a working connection to area 0 by the standard definition, it should not consider routes through non-backbone areas as valid. Cisco — Uses an alternative algorithm as documented in RFC 3509. This option allows routing though non-backbone areas when the backbone link is down. Standard — Uses the standard as defined in RFC 2328. Shortcut — Allows routing through non-backbone areas when they offer a better route. For details, see https://⁠www.ietf.org/archive/id/draft-ietf-ospf-shortcut-abr-02.txt.
Throttle Timer Settings section Throttle timers define the time between consecutive shortest path first (SPF) calculations. The initial delay is the time between an event triggering SPF calculation and the calculation being complete. Hold timers define the delay between SPF calculations. The timer increases from the initial hold time until the maximum hold time is reached. The hold time resets if SPF calculation is not triggered in adaptive hold time. This feature prevents SPF calculations from consuming resources.
Initial delay	Set the value for the `timers throttle spf delay` command in milliseconds.
Initial Hold Time	Set the value for the `timers throttle spf initial-holdtime` command in milliseconds.
Max Hold Time	Set the value for `timers throttle spf max-holdtime` in milliseconds.
Max Metric Router LSA section The link-state advertisement (LSA) metric settings can be used to route traffic around a router while it starts up or shuts down. This option causes transit links to be advertised at an infinite distance, causing the rest of the network to use alternative routes. This option requires redundant routes to be available.
On Startup	Set the value for the `max-metric router-lsa on-startup` command in seconds.
On Shutdown	Set the value for the `max-metric router-lsa on-shutdown` command in seconds.
Auto-Cost Reference Bandwidth	Set the value for the `auto-cost reference-bandwidth` command in megabits per second. This value is used in OSPF cost calculation.
Deprecated Path Reference Algorithm (RFC 1583 Compatibility)	Select this option for compatibility with RFC 1583. This option removes the routing loop prevention mechanism defined in RFC 2328. We do not recommend selecting this option.
Comment (Optional)	A comment for your own reference.
Category (Optional)	Includes the element in predefined categories. Click Select to select a category.
