BGP Attribute Tunning (Weight) {BGP Part 4 CCNP)

Weight

  Weight

Ø  Cisco Proprietary

Ø  Higher weight is better

Ø  In this scenario if we set the weight in R2 it does not leave from R2. It stay on Router2

2 Methods: - 1^st is to specify the weight for Specific neighbor and 2^nd is using route-map commands

  To define the weight for Specific neighbor

   In above scenario R2 Respectively have Two Gateways to reach outside network. So we will use R4 for Primary and R1 as Secondary. To do this we increase the Weight. By default weight is set to everything is 0

Ø  R2(config)#router bgp 65001

Ø  R2(config-router)#neighbor 100.100.100.10 description R4

Ø  R2(config-router)#neighbor 100.100.100.10 weight 10

Ø  R2#clear ip bgp * soft               Resetting the BGP Process to take affect

Ø  Show ip bgp                                   display the BGP information

Now test using “traceroute” from R2

All the Traffic from R2 will go from (R4 Gateway)
