TABLE 150 Output for the show ip bgp l2vpn vpls routes command
This field... Displays
Total number of BGP Routes The number of BGP4 routes the Brocade device has installed in the BGP4
route table.
Status A list of the characters the display uses to indicate the route’s status. The
status code appears in the last column of the display, to the right of each
route. The route’s status can be one or more of the following:
•
A: AGGREGATE – The route is an aggregate route for multiple
networks.
•
B: BEST – BGP4 has determined that this is the optimal route to the
destination.
•
b NOT-INSTALLED-BEST – The routes received from the neighbor are
the best BGP4 routes to their destinations, but were nonetheless not
installed in the IP route table because the Brocade device received
better routes from other sources (such as OSPF, RIP, or static IP
routes).
•
C: CONFED_EBGP – The route was learned from a neighbor in the
same confederation and AS, but in a different sub-AS within the
confederation.
•
D: DAMPED – This route has been dampened (by the route
dampening feature), and is currently unusable.
•
E: EBGP – The route was learned from another AS BGP neighbor.
•
F: FILTERED – The route was filtered from the BGP route table.
•
H: HISTORY – Route dampening is configured for this route, and the
route has a history of flapping and is unreachable now.
•
I: IBGP – The route was learned from the same AS BGP neighbor.
•
L: LOCAL – The route originated on this Brocade device.
•
M: MULTIPATH – BGP4 load sharing is enabled and this route was
selected as one of the best ones to the destination. The best route
among the multiple paths also is marked with “B”.
•
m: NOT-INSTALLED-MULTIPATH – The software was not able to install
the route in the IP route table.
•
S: SUPPRESSED – This route was suppressed during aggregation and
thus is not advertised to neighbors.
•
s: STALE – This is a stale route and is cleaned up.
Route Distinguisher A unique ID that is prepended on any address being routed or advertised
from a Virtual Routing and Forwarding (VRF) instance. The RD can be
defined as either ASN-relative or IP address-relative as described:
•
ASN-relative - Composed of the local ASN number followed by a “:”
(colon) and a unique arbitrary number. For example: 3:6
•
IP address-relative - Composed of the local IP address followed by a
“:” (colon) and a unique arbitrary number.
Prefix The IP address and network mask of the destination network of the route.
AS_PATH The BGP AS_PATH path attribute.
Next Hop The IP address of the next-hop router.
Metric The cost of this route.
LocPrf The degree of preference for this route relative to other routes in the local
AS. When the BGP4+ algorithm compares routes on the basis of local
preferences, the route with the higher local preference is chosen. The
preference can have a value from 0 – 4294967295.
