Border Gateway Protocol IPv4 (BGPv4) | 231
When dampening is applied to a route, its path is described by one of the following terms:
• history entry—an entry that stores information on a downed route
• dampened path—a path that is no longer advertised
• penalized path—a path that is assigned a penalty
The CLI example below shows configuring values to start reusing or restarting a route, as well as their
default values.
Figure 9-31. Setting Reuse and Restart Route Values
Dellconf-router_bgp)#bgp dampening ?
<1-45> Half-life time for the penalty (default = 15)
route-map Route-map to specify criteria for dampening
<cr>
Dell(conf-router_bgp)#bgp dampening 2 ?
<1-20000> Value to start reusing a route (default = 750)
Dell(conf-router_bgp)#bgp dampening 2 2000 ?
<1-20000> Value to start suppressing a route (default = 2000)
Dell(conf-router_bgp)#bgp dampening 2 2000 3000 ?
<1-255> Maximum duration to suppress a stable route (default = 60)
Dell(conf-router_bgp)#bgp dampening 2 2000 3000 10 ?
