Monitoring BGP
Use to display, after inbound policy is applied, all routes that originate from the
specified BGP neighbor.
Reports whether the indirect next hop of a route is unreachable; if not, displays
the IGP cost to the indirect next hop.
If you filter the display with field options, the usual introductory information
about BGP attributes is displayed only if you issue the intro fields option. See
show ip bgp for descriptions of the fields displayed by this keyword.
Field descriptions
Local router ID BGP router ID of the local router
local AS Local autonomous system number
paths Total number of routes stored in the BGP routing table. If several
peers have advertised a route to the same prefix, all routes are included in
this count.'
distinct prefixes 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.
paths 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.
Local-RIB version Number that is increased by one each time a route in
that RIB is added, removed or modified.
FIB version Number that is increased by one each time BGP updates the
routes in the IP routing table based on changes in the local RIB. The FIB
version matches the local-RIB version when BGP has finished updating the
routes in the IP route table. The FIB version is less than the local-RIB version
when BGP is still in the process of updating the IP routing table.
Prefix Prefix for the routing table entry
Peer IP address of BGP peer
Next-hop IP address of the next hop
MED Multiexit discriminator
CalPrf Calculated preference
Weight Assigned path weight
Origin Origin of the route
Example
host1#show bgp ipv6 neighbors 12.12.12.12 routes
Local BGP identifier 11.11.11.11, local AS 400
