Monitoring Routes Originating from a BGP Neighbor Before Application of Inbound Policy
Purpose
Display routes originating from the specified BGP neighbor before inbound policy is applied. 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 received-routes and show bgp ipv6 neighbors received-routes commands display similar information.
Action
To display routes originating from the specified BGP neighbor before inbound policy is applied:
host1#show ip bgp neighbors 192.168.1.158 received-routes Local BGP identifier 111.111.111.111, local AS 444 0 routes (0 bytes used), 0 distinct destinations (0 bytes used) 0 routes selected for route table installation 0 path attribute entries (0 bytes used) Status codes: > best, * invalid, s suppressed, d dampened, r rejected Prefix Peer Next-hop MED LocPrf Weight Origin >0.0.0.0/0 192.168.1.158 192.168.1.158 0 IGP >13.13.13.13/32 192.168.1.158 192.168.1.158 0 0 IGP
Meaning
Table 39 lists the show ip bgp neighbors received-routes command output fields.
Table 39: show ip bgp neighbors received-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 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 |
