Resetting BGP Connections

After completing the BGP configuration, you can warm reset or reset BGP connection so that the new configuration takes effect. Resetting a BGP connection interrupts the VPN service. Exercise caution when performing this operation.

Soft reset means that after a BGP configuration policy is changed, the system can automatically refresh the BGP routing table without interrupting a BGP connection.

If a BGP peer supports route-refresh, run the refresh bgp command to manually warm reset a BGP connection to refresh the BGP routing table.
If a BGP peer does not support route-refresh, run the peer keep-all-routes command for the peer to refresh the BGP routing table.

To reset a BGP connection, run the reset command, which interrupts the VPN service.

Run the commands listed in Table 1 in the user view to warm reset or reset BGP connections so that the new configurations take effect.
