In BGP, the local-preference attribute is used to prefer one path over another for outbound traffic. The local-preference attribute is not sent to external BGP (eBGP) peers; it is an attribute evaluated within the local AS. The issue in the provided configuration is that the route-map SETLP is applied in the outbound direction, which is ineffective since local-preference does not leave the AS. To resolve the issue, the route-map SETLP should be applied in the inbound direction (route-map SETLP in), allowing the local-preference attribute to influence route selection for traffic leaving AS 65500.
