2. Configure BGP neighbors. This example uses passive peering which simplifies neighbor configuration.
Spine1(config)# router bgp 65101
Spine1(config-router-bgp-65101)# router-id 10.0.0.1
Spine1(config-router-bgp-65101)# template passive_v4_pod1
Spine1(config-router-template)# remote-as 65201
Spine1(config-router-template)# listen 10.1.1.0/24
Spine1(config-router-template)# exit
Spine1(config-router-bgp-65101)# template passive_v4_pod2
Spine1(config-router-template)# remote-as 65202
Spine1(config-router-template)# listen 10.1.2.0/24
Spine1(config-router-template)# exit
