3.16.6 Debugging BGP/MPLS IP VPN
Run the relevant debugging command to view the debugging information and locate the fault.
Note that debugging affects the performance of the system.
Context
CAUTION
Debugging affects system performance. After debugging is complete, run the undo debugging
all command to disable debugging immediately.
Run the following debugging commands in the user view to debug BGP/MPLS IP VPN and
locate the fault.
For more information, see the chapter "Information Center Configuration" in the S7700 Smart
Routing Switch Configuration Guide - System Management. For the description about the
debugging commands, see the Quidway S7700 Smart Routing Switch Debugging Reference.
Procedure
l Run the debugging bgp vpn-instance vpn-instance-name peer-address { all | event |
graceful-restart | timer } command in the user view to enable the debugging of the
specified BGP peers in a VPN instance.
l Run the debugging bgp vpn-instance vpn-instance-name peer-address { keepalive |
open | packet | raw-packet | route-refresh } [ receive | send ] [ verbose ] command in
the user view to enable the packet debugging of the specified BGP peers in a VPN instance.
l Run the debugging bgp update vpn-instance vpn-instance-name [ peer ip-address | acl
acl-number | ip-prefix ip-prefix-name ] [ receive | send ] [ verbose ] command in the user
view to enable the BGP Update packets debugging of VPN instances.
l Run the debugging bgp update vpnv4 [ peer ip-address | acl acl-number | ip-prefix ip-
prefix-name ] [ receive | send ] [ verbose ] command in the user view to enable the BGP
Update packets debugging of BGP VPNv4 routes.
l Run the debugging bgp update label-route [ peer ip-address ] [ acl acl-number | ip-
prefix ip-prefix-name ] [ receive | send ] [ verbose ] command in the user view to enable
the BGP Update packets debugging of labeled routes.
