Turn off next-hop route data collection for BGP routers

task brazil Updated Sep 10, 2026 1 min read turn-off-bgp-next-hop-collection.md

You can turn off Next Hop Routing Rule [dscy_route_next_hop] table collection for BGP-enabled routers to reduce MID Server memory load during router discovery.

Before you begin

Verify that you have at least version 1.35.1 of Discovery and Service Mapping Patterns.
Navigate to sys_properties.list and verify that the glide.discovery.bgp_router_disable property is set to false.

Role required: discovery_admin

About this task

By default, the glide.discovery.bgp_router_disable property is set to true, blocking the entire BGP routing branch including interfaces and neighbors. Setting the property to false enables interface and neighbor collection but also triggers a full route-table walk. On routers with large route tables, this can cause MID Server memory and performance issues.

The glide.discovery.disable_next_hop_data property controls route-table collection. When this property is set to true, Discovery collects the device, physical interfaces, and neighbors but skips populating the Next Hop Routing Rule [dscy_route_next_hop] table. The default value is false.

Procedure

In the navigation filter, enter sys_properties.list.
In the Name column, search for glide.discovery.disable_next_hop_data.
Select the glide.discovery.disable_next_hop_data system property.
In the Value field, enter true.

To also collect next-hop route table data, set the value to false.
Select Update.

What to do next

Run Discovery again against a BGP-enabled router to apply the changes.

# Turn off next-hop route data collection for BGP routers

You can turn off Next Hop Routing Rule \[dscy\_route\_next\_hop\] table collection for BGP-enabled routers to reduce MID Server memory load during router discovery.

## Before you begin

- Verify that you have at least version 1.35.1 of Discovery and Service Mapping Patterns.
- Navigate to `sys_properties.list` and verify that the **glide.discovery.bgp\_router\_disable** property is set to false.
