# Monitoring Dampened BGP Routes of Specified Neighbors

#### Purpose

Display information about routes with a dampening history for the specified BGP neighbor. Report whether the indirect next hop of a route is unreachable; if not, display the IGP cost to the indirect next hop.

The show ip bgp neighbors dampened-routes and show bgp ipv6 neighbors dampened-routes commands display similar information.

#### Action

To display information about routes with a dampening history for the specified BGP neighbor:

    host1#show ip bgp neighbors 192.168.1.158 dampened-routes
    Local BGP identifier 192.168.1.232, local AS 100
      120 routes (5760 bytes used), 94 distinct destinations (9024 bytes used)
      67 routes selected for route table installation
      23 path attribute entries (3450 bytes used)

    Status codes: > best, * invalid, s suppressed, d dampened, r rejected

#### Meaning

Table 36 lists the show ip bgp neighbors dampened-routes command output fields.

Table 36: show ip bgp neighbors dampened-routes Output Fields

Field Name | Field Description
--- | ---
Local BGP identifier | BGP router ID of the local router
local AS | Local autonomous system number
routes | Total number of routes stored in the BGP routing table and amount of memory consumed by routes. If several peers have advertised a route to the same prefix, all routes are included in this count.
distinct destinations | Number of routes to unique prefixes stored in the BGP routing table. If several peers have advertised a route to the same prefix, only the best route is included in this count.
routes selected for route table installation | Number of routes in the BGP routing table that have been inserted into the IP routing table
path attribute entries | Number of distinct path attributes stored in BGP's internal path attributes table. If BGP receives two routes for different prefixes but with identical path attributes, BGP will create only one entry in its internal path attribute table and share it between the two routes to conserve memory.
Prefix | Prefix for the routing table entry
Peer | IP address of BGP peer
Next hop IP address | IP address of the next hop
MED | Multiexit discriminator for the route
LocPrf | Local preference for the route
Weight | Assigned path weight
Origin | Origin of the route
