The autonomous systems configured in this command are visible to the EBGP
neighbors. Each autonomous system is fully meshed and contains a few
connections to other autonomous systems.
After specifying autonomous systems numbers for the BGP confederation, recycle
the peers to update their configuration.
This command automatically restarts the BGP instance for the configuration to
take effect.

Parameters
half-life
(OPTIONAL) Enter the number of minutes after which the
Penalty is decreased. After the router assigns a Penalty of
1024 to a route, the Penalty is decreased by half after the
half-life period expires. The range is from 1 to 45. The default
is
15 minutes
.
reuse
(OPTIONAL) Enter a number as the reuse value, which is
compared to the flapping route’s Penalty value. If the Penalty
value is less than the reuse value, the flapping route is once
again advertised (or no longer suppressed). The range is from
1 to 20000. The default is
750
.
suppress
(OPTIONAL) Enter a number as the suppress value, which is
compared to the flapping route’s Penalty value. If the Penalty
value is greater than the suppress value, the flapping route is
no longer advertised (that is, it is suppressed). The range is
from 1 to 20000. The default is
2000
.
max-suppress-
time
(OPTIONAL) Enter the maximum number of minutes a route
can be suppressed. The default is four times the half-life
value. The range is from 1 to 255. The default is
