Configuring BGP4 neighbors

shutdown administratively shuts down the session with this neighbor. Shutting down the session
lets you configure the neighbor and save the configuration without actually establishing a session
with the neighbor.
When a peer is put into the shutdown state, ribout routes are not produced for that peer. You can
elect to produce ribout routes using the generate-rib-out option. This option is disabled by default.
soft-reconfiguration inbound enables the soft reconfiguration feature, which stores all the route
updates received from the neighbor. If you request a soft reset of inbound routes, the software
performs the reset by comparing the policies against the stored route updates, instead of
requesting the neighbor BGP4 route table or resetting the session with the neighbor. Refer to
“Using soft reconfiguration” on page 267.
static-network-edge controls the advertisement of a static BGP4 network to BGP4 neighbors that
are configured as Service Edge Devices.
timers keep-alive num hold-time num overrides the global settings for the Keep Alive Time and Hold
Time. For the Keep Alive Time, you can specify 0 – 65535 seconds. For the Hold Time, you can
specify 0 or a number in the range 3 – 65535 (1 and 2 are not allowed). If you set the Hold Time to
0, the device waits indefinitely for messages from a neighbor without concluding that the neighbor
is non-operational. The defaults for these parameters are the currently configured global Keep Alive
Time and Hold Time. For more information about these parameters, refer to
“Changing the Keep
Alive Time and Hold Time” on page 243.
unsuppress-map map-name removes route suppression from neighbor routes when those routes
have been suppressed due to aggregation. Refer to
“Removing route dampening from suppressed
routes” on page 233.
update-source ip-addr | ethernet slot/portnum | pos slot/portnum | loopback num | ve num
configures the device to communicate with the neighbor through the specified interface. There is
no default.
weight num specifies a weight the device will add to routes received from the specified neighbor.
BGP4 prefers larger weights over smaller weights. The default weight is 0.
Auto shutdown of BGP4 neighbors on initial
configuration
You can use the global auto-shutdown-new-neighbors command within the router bgp configuration
to disable establishment of the BGP4 connection with a remote peer when the peer is first
configured, as follows.
Virtual ADX(config)# router bgp
Virtual ADX(config-bgp-router)# auto-shutdown-new-neighbors
Once all of the configuration parameters for the peer are complete, you can start the BGP4 session
establishment process using the no option with the existing peer shutdown option command to
disable the peer shutdown state.
Virtual ADX(config)# router bgp
Virtual ADX(config-bgp-router)# no neighbor 10.1.1.1 shutdown
Syntax: [no] neighbor ip-address shutdown
If auto shutdown of BGP4 neighbors is enabled and you want to disable it to allow a new BGP4 peer
configured to establish a connection with remote peers, use the no option with the command.
