The route 6.6.6.6/32 is being learned via R6 and we are going to try to influence the routing decision on R2 to take the path via the longer AS path through R4 and R5. Follow this BGP tutorial I will be using the simple topology below. It is the second attribute in the BGP best path algorithm with BGP Weight being the first. The BGP Local Preference attribute or local-pref is used to influence the outbound routing decision of a router running BGP. The BGP preference has to be set inbound on routes being received to influence the outbound routing behaviour.Ī higher local preference is preferred and the default is 100. Local preference is the second BGP attribute and is used to choose the exit path for an autonomous system.
