best
Optimal route.
select
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
Active route.
pre 255
Protocol priority of the route: 255

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
