Resetting BGP Connections

Resetting BGP Connections

Context

VPN services are interrupted after the BGP connection is reset. Exercise caution when running the commands.

When the BGP configuration changes, you can perform a soft reset or normal reset operation to reset BGP connections. This allows the new configurations to take effect. A soft reset requires that the BGP peers have route refreshment capability (supporting Route-Refresh messages).

Procedure

  • Run the refresh bgp vpn-instance vpn-instance-name ipv4-family { all | ipv4-address | group group-name | internal | external } import command in the user view to trigger the inbound soft reset of the BGP connection for the VPN instance IPv4 address family.
  • Run the refresh bgp vpn-instance vpn-instance-name ipv4-family { all | ipv4-address | group group-name | internal | external } export command in the user view to trigger the outbound soft reset of the BGP connection for the VPN instance IPv4 address family.
  • Run the refresh bgp vpnv4 { all | ipv4-address | group group-name | internal | external } import command in the user view to trigger the inbound soft reset of the BGP VPNv4 connection.
  • Run the refresh bgp vpnv4 { all | ipv4-address | group group-name | internal | external } export command in the user view to trigger the outbound soft reset of the BGP VPNv4 connection.
  • Run the reset bgp vpn-instance vpn-instance-name ipv4-family { as-number | ipv4-address | group group-name | all | internal | external } command in the user view to reset BGP connections of the VPN instance IPv4 address family.
  • Run the reset bgp vpnv4 { as-number | ipv4-address | group group-name | all | internal | external } command in the user view to reset BGP VPNv4 connections.
