no bgp default local-preference
<value>
When routes are advertised to the peers, IBGP peers and the ex-
ternal peers in the confederation has already been included in the
peers. This command configures the local-preference value of the
route to affect the route decision (tie_break) of the peers. If the
other peers obtain the advertised routes and the local-preference
value exists, this value will not overwrite the existing value.
This example describes how to configure the local preference of
the routes advertised by the BGP as 500.
ZXR10(config)#router bgp 1
ZXR10(config-router)#bgp default local-preference 500

The route-target attribute filtering is supported by default.
The BGP extension supports the MPLS-VPN application. In general,
the vpnv4 routes should match the route-target attribute, but this
route-target attribute filtering needs enabling for the applications
of the route reflector, or across-domain EBGP.
This example describes how to configure BGP not to filter route
target attribute.
ZXR10(config)#router bgp 1
ZXR10(config-router)#no bgp default route-target filter
