(Optional) Configuring the Function for Logging Route Quantity Threshold-Crossing

(Optional) Configuring the Function for Logging Route Quantity Threshold-Crossing

Configuring the function of logging route quantity threshold-crossing helps monitor the impact of an increase in route quantity on memory. When the number of routes exceeds the configured threshold, reduce the number of local access hosts.

Usage Scenario

In distributed VXLAN gateway scenarios, EVPN serves as the control plan to deliver routes. As more and more hosts access the gateway, routes stored on the control plane increase greatly, consuming a lot of memory resources. After the function is configured, a user log is generated when the number of routes exceeds the threshold.

Procedure

  • Set a threshold and log recovery percentage for the number of EVPN routes.

    1. Run system-view

      The system view is displayed.

    2. Run bgp as-number [ instance instance-name ]

      The BGP or BGP multi-instance view is displayed.

    3. Run l2vpn-family evpn

      The BGP-EVPN address family view or BGP multi-instance EVPN address family view is displayed.

    4. Run alarm-threshold route route-number [ recovery-percentage percentage ]

      A threshold and log recovery percentage are set for the number of EVPN routes.

      By default, the threshold and log recovery percentage for the number of EVPN routes are not configured.

    5. Run commit

      The configuration is committed.

  • Set a threshold and log recovery percentage for the number of routes in a VPN instance.

    1. Run system-view

      The system view is displayed.

    2. Run alarm-threshold route route-number [ recovery-percentage percentage ] { ipv4 | ipv6 } vpn-instance vpn-instance-name

      A threshold and log recovery percentage are set for the number of routes in a VPN instance.

      By default, the threshold and log recovery percentage for the number of routes in an L3VPN instance are not configured.

    3. Run commit
