config bgp neighbor [<ipaddress> | all] weight
<weight>
Assigns a locally used weight to a neighbor
connection for the route selection algorithm. All
routes learned from this peer are assigned the
same weight. The route with the highest weight
is more preferable when multiple routes are
available to the same network. The range is 0
to 4294967295. The default setting is 0.
config bgp router-id <router_id> Changes the router ID. BGP must be disabled
before changing the router ID.
config bgp soft-reconfiguration Applies the route map associated with the
network command, aggregation and
redistribution, immediately. This command
does not affect the switch configuration.
create bgp neighbor <ipaddress> remote-as
<as_number> {multihop}
Creates a new BGP peer. Use the multihop
keyword for EBGP peers that are not directly
connected.
disable bgp aggregation Disables BGP route aggregation filtering.
disable bgp always-compare-med
disable bgp export [ospf | ospf-intro | ospf-inter
| ospf-extern1 | ospf-extern2]}
Disables BGP from export OSPF-related routes
to other BGP peers.
enable bgp Enables BGP.
enable bgp aggregation Enables BGP route aggregation.
enable bgp aggregation Enables BGP route aggregation filtering.
enable bgp always-compare-med Enables BGP to use the Multi Exit
Discriminator (MED) from neighbors in different
autonomous systems in the route selection
algorithm. MED is only used when comparing
paths from the same AS. The default setting is
enabled.
enable bgp compare-as-path Enables using the As path as a factor in the
route selection algorithm. The default setting is
enabled.
enable bgp compare-med-within-as-only Enables BGP to use the MED as a factor in
the route selection algorithm from
confederation peers. The default setting is
disabled.
enable bgp neighbor [<ipaddress> | all] Enables the BGP session. The neighbor must
be created before the BGP session can be
enabled.
