29.9.4 LOCAL_PREF Attribute Related
Configuration
The BGP takes the LOCAL_PREF as the foundation to compare with the priority of the path
learned from the IBGP Peers. The larger the LOCAL_PREF value, the higher the priority of
the path is.
The BGP Speakers will add the local preference when they send the received external route
to the IBGP Peers. To modify the local preference, execute the following operations in the
BGP configuration mode:
Command
Router(config-router)# bgp default
local-preference value
You can also modify the local preference of specified path by the set local-preference
command of Route-map.
29.9.5 COMMUNITY Attribute Related
Configuration
COMMUNITY Attribute is another method to control the distribution of the route information.
The community is a set of the destinations. The purpose of the definition for the community
attribute is to implement the community-based routing strategy, so as to simplify the
configuration to control the distribution of the route information in the BGP Speakers.
Each destination may be of more than one community, and the manager of the AS can
define which community the destination is of.
By default, all destinations are of the Internet community, carried in the community attribute
of the path.
At present, total for four common community attribute values are predefined:
Internet: Indicate the Internet community, and all paths are of this community.

no-export: Indicate this path will not be issued to the \BGP peers.

no-export: Indicate this path will not be issued to the BGP peers.

Meaning
(Optional) Allow to compare with the path of the peers
from the same AS firstly. By default, they will be
compared with by the received sequence, the later
received path will be compared with firstly.
Meaning
(Optional) Change the default local preference.
The range of the value is 0~4294967295, 100 by
