Monitoring and Maintaining SSO-BFD Chapter 18 SSO-BFD Monitoring and Maintaining SSO-BFD The BFD packets are dropped if there is a problem on the link and the BFD signals its client. A corresponding action occurs to bring down the feature. However, during a switchover, if the peer router goes down, the router undergoing the switchover detects the failure when the CEF path comes up. To monitor and maintain the SSO-BFD feature, enter any of the following commands in privileged EXEC mode: Command Router# show enhanced-timers Router# show bfd neighbour detail Router# debug bfd ha Router# debug bfd event Router# debug bfd packet Purpose Displays status of the values set on the timers. This command is used on the standby PRE. Displays complete details of the BFD neighbor including the routing protocol registered with it. This command is used on the active PRE. Displays logs specific to the BFD HA process. The command can also be used to check whether there is a failure in transmission of BFD packets during a switchover causing the peer router to detect a failure. This command can be enabled on the standby PRE also. Checks for packets received or lost from the router undergoing a switchover. Checks whether the router undergoing a switchover failed to transmit BFD packets. Configuration Examples of SSO-BFD This section explains the following configuration examples: • SSO-BFD with Static: Example, page 18-73 • SSO-BFD with BGP: Example, page 18-75 • SSO-BFD with EIGRP: Example, page 18-79 • SSO-BFD with ISIS: Example, page 18-82 • SSO-BFD with OSPF: Example, page 18-84 Note The following BFD timers are supported for the SSO-BFD feature: • bfd interval 999 min_rx 999 multiplier 5 • bfd interval 999 min_rx 999 multiplier 6 • bfd interval 500 min_rx 500 multiplier 8 Note The [no] bfd echo command is configured to enable or disable the echo mode. When the echo mode is enabled, the no ip redirect command must be configured under interfaces that are enabled with the BFD protocol. 18-72 Cisco 10000 Series Router Software Configuration Guide OL-2226-23
