The display bgp routing-table network [ { mask | mask-length } [ longer-prefixes ] ] command
output varies with the route generation mode and transmission mode, and not all BGP attributes
are necessarily displayed. In the preceding example, the route type is not displayed because the
route 12.13.14.15/32 is an IBGP route. If you run the display bgp routing-table network
[ { mask | mask-length } [ longer-prefixes ] ] command, the route type will be displayed. For
example:

Description
QoS information.
AS_Path attribute. If Nil is displayed, the AS_Path attribute is null.
Origin attribute:
l IGP: indicates that routes are added to the BGP routing table using
the network (BGP) command.
l EGP: indicates that routes are learned through the EGP protocol.
l Incomplete: indicates that routes are imported using the import-
route (BGP) command.
MED value of a BGP route, similar to the cost of IGP routes.
Local_Pref
PrefVal
Valid route with a reachable next hop address.
Type of the peer from which the route is learned.
l external: indicates that the route is learned from an EBGP peer.
l internal: indicates that the route is learned from an IBGP peer.
Optimal route.
Selected route to be delivered to the IP routing table.
NOTE
According to BGP selection rules, BGP selects only one optimal route, and this
route is marked with best. In load balancing or FRR scenarios, more than one
route needs to be added to the IP routing table, and each of the route is marked
with select. Therefore, the number of the route marked with best is 1, and the
number of the routes marked with select is the actual number of routes added to
the IP routing table.
Active route.
Protocol priority of the route: 255
IGP cost.
AIGP
The route has not advertised to any peer yet.
