nexthop recursive-lookup delay

Function

The nexthop recursive-lookup delay command configures the delay in responding to changes of the next hop.

The undo nexthop recursive-lookup command restores the default setting.

Usage Guidelines

If the routes on which BGP routes depend for iteration change frequently, you can run the nexthop recursive-lookup delay command to configure a delay for the BGP routes to respond to the changes, which prevents unnecessary routes re-selection and re-advertisement.

Example

# Set the delay in responding to changes of the next hop to 10s.

<sysname> system-view

[sysname] bgp 100

[sysname-bgp] nexthop recursive-lookup delay 10
