Configuring the Routing Protocols Used for Network Proximity Configuring BGP for Proximity Calculations SUMMARY STEPS 1. router bgp as-no 2. location-community community-string weight weight 3. log-neighbor-changes 4. neighbor ip-address timers keepalives holdtime 5. neighbor ip-address ebgp-multihop 6. neighbor ip-address remote-as as-no 7. neighbor ip-address password string 8. ip urib bgp bestpath DETAILED STEPS Step 1 Step 2 Step 3 Step 4 Command or Action router bgp as-no Example: switch(config)# router bgp 3 Purpose Configures the BGP routing process and enters routing configuration mode. • as-no-Number of an autonomous system that identifies the router to other BGP routers and tags routing information that is passed along. location-community community-string weight weight Configures the community values that are associated with the proximity engine. Example: switch(config-router)# location-community 11:222 weight 100 • community-string-String associated with the proximity engine. • weight-Weighting associated with the community. log-neighbor-changes Enables logging of BGP neighbor resets. Example: switch(config-router)# log-neighbor-changes neighbor ip-address timers keepalives holdtime Example: switch(config-router)# neighbor 26.0.0.1 timers 30 100 Configures the timers for a specific BGP peer or peer group. • ip-address-BGP peer or peer group IP address. • keepalives-Frequency, in seconds, with which the BGP process sends keepalive messages to its peer. The default is 60. The range is from 0 to 65535. • holdtime-Interval, in seconds, after not receiving a keepalive message that the process declares a peer dead. The default is 180. The range is from 3 to 65535. The hold time must be more than twice the keepalive interval.
