If the router is configured for the BGP EVPN address family, this command will return output. To determine whether the device is configured for the BGP EVPN address family, use the show running-config | section router bgp | address-family l2vpn evpn EXEC command in the CLI. If the device returns output, proceed to the next step.ĭetermine Whether the Device Is Configured for the L2VPN EVPN Address Family
If the command returns no output, or the command returns an error, the device is not affected by this vulnerability. The following example shows the partial output of the show running-config | section router bgp command on a device that is configured for BGP routing: router# show running-config | section router bgp If the router is configured for BGP, this command will return output. To determine whether the device is configured for BGP routing, use the show running-config | section router bgp EXEC command in the CLI.
To determine whether the device has a vulnerable configuration, assess the BGP routing configuration and then the L2VPN EVPN address family status (if necessary).ĭetermine Whether the Device Is Configured for BGP Routing
