BGP Auto-peering Simple Leaf/Spine Example

The following example shows a simple leaf/spine topology with users on VLANs, red and blue, noted as 1 and 2.

Note

An Advanced Edge or Base license must be installed on all devices.

Devices labeled with router IDs 10.255.x.y:

Leaf 1

configure vlan default delete ports 1-2
create vlan “red" tag 100
configure vlan red add ports 1 untagged
configure vlan "red" ipaddress 10.1.1.1/24
enable ipforwarding vlan "red"

create vrrp vlan "red" vrid 1
configure vrrp vlan "red" vrid 1 priority 255
configure vrrp vlan "red" vrid 1 host-mobility on
configure vrrp vlan "red" vrid 1 add 10.1.1.254
enable vrrp vlan "red" vrid 1

create vlan "blue" tag 200
configure vlan "blue" ipaddress 10.1.2.1/24
configure vlan blue add ports 2 untagged
enable ipforwarding vlan "blue"

create vrrp vlan "blue" vrid 1
configure vrrp vlan "blue" vrid 1 priority 255
configure vrrp vlan "blue" vrid 1 host-mobility on
configure vrrp vlan "blue" vrid 1 add 10.1.2.254
enable vrrp vlan "blue" vrid 1
