1. Configure switch interfaces with assigned IP addresses.
On SW1
net add interface swp1 ip address 10.0.0.1/30 net add loopback lo ip address 1.1.1.1/32 net commit
On SW2
net add interface swp1 ip address 10.0.0.2/30 net add loopback lo ip address 2.2.2.2/32 net commit
2. Verify layer 3 connectivity between the two switches. Noting that for BGP to work you require connectivity to your neighbour.
On SW1
ping 10.0.0.1
On SW2
ping 10.0.0.2
3. Configure your local BGP Autonomous System Number.
On SW1
net add bgp autonomous-system 1000 net add bgp router-id 1.1.1.1 net add bgp neighbor 2.2.2.2 remote-as external net add bgp neighbor 2.2.2.2 ttl-security hops 2 net add bgp neighbor 2.2.2.2 update-source loopback net add bgp network 10.0.0.0/24 net add bgp network 20.0.0.0/24
