11. If you wish, specify appropriate values for the options on the Advanced tab according
to the guidelines in the following table:
Table 38. BGP Peer-Group advanced options
Option Description
Metric Out Specifies the primary metric used on all routes sent to the
specified peer group. The metric hierarchy is as follows
(from highest to lowest priority/preference):
• The metric specified by export policy
• Peer-level metric out
• Group-level metric out
• Default metric
Gated Preference Allows GateD to use the LOCAL_PREF attribute to set
preference on reception, and allows the GateD preference to
set the LOCAL_PREF on transmission. The set-pref metric
works as a lower limit, below which the imported
LOCAL_PREF may not set the GateD preference.
Note:
This option is designed to be used with internal,
routing, and IGP peer groups.
Route Preference Specifies the preference used for routes learned from these
peers. This can differ from the default BGP preference set in
the BGP set preference statement, so that GateD can prefer
routes from one peer, or group of peer, over others. This
preference may be explicitly overridden by import policy.
Local Address Specifies the address to be used on the local end of the TCP
connection with the peer or with the peer's gateway when the
gateway option is used. A session with an external peer will
only be opened when an interface with the appropriate local
address (through which the peer or gateway address is
directly reachable). In either case incoming connections will
only be recognized as matching a configured peer if they are
addressed to the configured local address.
Note:
This option is designed to be used with internal,
routing, and IGP peer groups and should be a valid,
active interface address.
