Related Commands The higher the administrative distance assigned to a route means that your confidence in that route is low. Routes assigned an administrative distance of 255 are not installed in the routing table. Routes from confederations are treated as internal BGP routes. router bgp - enters ROUTER mode on the switch. show ip bgp dampened-paths View BGP routes that are dampened (non-active). C9000 Series Syntax Parameters show ip bgp [vrf vrf-name] [ipv4 {multicast | unicast} | ipv6 unicast] dampened-paths vrf vrf-name ipv4 multicast ipv4 unicast ipv6 unicast (OPTIONAL) Enter the keywords vrf and then the name of the VRF to view routes that are affected by a specific community list corresponding to that VRF. (OPTIONAL) Enter the keyword ipv4 followed by the keyword multicast to view information related only to ipv4 multicast routes. (OPTIONAL) Enter the keywords ipv4 followed by the keyword unicast to view information related only to ipv4 unicast routes. (OPTIONAL) Enter the keyword ipv6 followed by the keyword unicast to view information related only to ipv6 unicast routes. Command Modes ● EXEC ● EXEC Privilege Command History Usage Information This guide is platform-specific. For command information about other platforms, refer to the relevant Dell Networking OS Command Line Reference Guide. The following is a list of the Dell Networking OS version history for this command. Version Description 9.9(0.0) 9.8(0.0) 9.7(0.0) 9.4(0.0) 9.0.2.0 8.3.19.0 8.3.11.1 8.3.7.0 7.8.1.0 7.7.1.0 Introduced on the C9010. Introduced on the S3048-ON and S4048-ON. Added the ipv4 multicast and ipv6 unicast parameters. Added support for VRF. Introduced on the S6000. Introduced on the S4820T. Introduced on the Z9000. Introduced on the S4810. Introduced on the S-Series. Introduced on the C-Series. To determine a BGP session flap, both a route-down event and a subsequent route-up event corresponding to a single route are considered. As a result, a flap event is penalized only one time during the route-down event. The subsequent route-up event corresponding to the same route is not considered as a flap and is not penalized. The history paths that the show ip bgp command displays contain only the prefix and the next-hop information. The next-hop information shows the ip address of the neighbor. It does not show the actual next-hop details. Border Gateway Protocol 427

Usage

Information

To determine a BGP session flap, both a route-down event and a subsequent route-up event

corresponding to a single route are considered. As a result, a flap event is penalized only one time during

the route-down event. The subsequent route-up event corresponding to the same route is not considered

as a flap and is not penalized.

The history paths that the

show ip bgp

command displays contain only the prefix and the next-hop

information. The next-hop information shows the ip address of the neighbor. It does not show the actual

next-hop details.
