13-24 config bgp neighbor general
Description
This command is used to configure the BGP neighbor's general setting.
ebgp_multihop: This specifies the TTL of the BGP packet sent to the neighbor. If it is specified as
1, it will have a restriction that the neighbor must be directly connected to it.
weight: This specifies the weight that will be associated to the routes learned from the specified
neighbor. The route with highest weight will be chosen as the preferred route. If the route map sets
weight to a route, then this route map specified weight will override the weight specified by the
BGP neighbor's command. Weight is an attribute which is specified in the ingress direction, and is
not an attribute to be advertised with the route. It is used to specify preference to routes received
from a neighbor over another neighbor.
soft_reconfiguration_inbound: If the setting is enabled, the route updates sent from the
specified neighbor will be stored. This storage is required for inbound soft reconfiguration. When a
soft reset is requested for inbound sessions, the session will not be torn down, but the inbound
routing table will be cleared. It needs to be rebuilt. If the soft reconfiguration inbound is enabled,
then the routing table can be rebuilt based on the stored route update information. If the soft
reconfiguration inbound is disabled, then the local router will send the route refresh requests to the
neighbor to ask for the route refresh.
next_hop_self: If the next_hop_self option is enabled, the router will set the next_hop to itself
when it advertises the routes to the specific neighbor. If the next_hop_self option is disabled, the
next_hop attributes will not be changed. The behavior described here will be overridden by the set
next hop statement if route map is applied to the neighbor in the out direction.
remove_private_as: The private Autonomous System numbers are from 64512 to 65535. If this
setting is set to enable, the private AS number in AS path attribute of the BGP update packets will
be dropped.
allowas_in: The BGP router will do AS path loop checks for the received BGP update packet. If
the BGP router's self AS appears in the AS path, it is identified as a loop and the packet will be
discarded. If the allow-as setting is enabled, the BGP router's self AS is allowed in the AS path list.
default_originate: If this setting is enabled, it will allow a BGP speaker (the local router) to send
the default route 0.0.0.0/0 to a neighbor to use as the default route. If route map is specified, the
default route will be injected if the route map contains a match IP address statement. If this setting
is disabled, no default route will be sent to the neighbor. The default setting is disabled.
