# Leaf 2 configuration
|
|
|
|
## Pre-config Setup
|
|
|
|
Disable ZeroTouch provisioning :
|
|
|
|
```config
|
|
en
|
|
zerotouch cancel
|
|
```
|
|
|
|
Enable the multi-agent configuration on Arista switch to be able to use EVPN feature
|
|
|
|
```config
|
|
en
|
|
conf
|
|
service routing protocols model multi-agent
|
|
```
|
|
|
|
Enabling IP Routing
|
|
|
|
```config
|
|
conf
|
|
ip routing
|
|
```
|
|
|
|
## IP address Configuration
|
|
|
|
Configure need to match with [Lab Topology](../../lab_vxlan.yml)
|
|
|
|
```yml
|
|
links:
|
|
- endpoints: ["spine1:eth1", "leaf1:eth1"]
|
|
- endpoints: ["spine1:eth2", "leaf2:eth1"]
|
|
- endpoints: ["leaf1:eth2", "host1:eth1"]
|
|
- endpoints: ["leaf2:eth2", "host2:eth1"]
|
|
```
|
|
|
|
That means :
|
|
|
|
```config
|
|
interface Ethernet1
|
|
description TO_SPINE01
|
|
no switchport
|
|
ip address 10.1.1.3/31
|
|
!
|
|
interface Ethernet2
|
|
description TO_HOST2
|
|
switchport mode trunk
|
|
!
|
|
interface Loopback0
|
|
description VTEP
|
|
ip address 10.10.110.2/32
|
|
!
|
|
```
|
|
|
|
## BGP Protocol
|
|
|
|
```config
|
|
router bgp 65102
|
|
router-id 10.10.110.2
|
|
maximum-paths 4 ecmp 4
|
|
neighbor SPINE_GROUP peer group
|
|
neighbor SPINE_GROUP allowas-in 1
|
|
neighbor SPINE_GROUP ebgp-multihop 4
|
|
neighbor SPINE_GROUP send-community extended
|
|
neighbor SPINE_GROUP maximum-routes 12000
|
|
neighbor 10.1.1.2 peer group SPINE_GROUP
|
|
neighbor 10.1.1.2 remote-as 65001
|
|
!
|
|
address-family ipv4
|
|
neighbor 10.1.1.0 activate
|
|
```
|
|
|
|
To check peer status :
|
|
|
|
```cli
|
|
show bgp summary
|
|
```
|
|
|
|
## BGP EVPN Overlay
|
|
|
|
```config
|
|
interface Loopback0
|
|
description VTEP
|
|
ip address 10.10.110.2/32
|
|
!
|
|
ip prefix-list VTEP_PREFIX seq 10 permit 10.10.110.2/32
|
|
!
|
|
route-map RMAP_VTEP permit 10
|
|
match ip address prefix-list VTEP_PREFIX
|
|
!
|
|
router bgp 65102
|
|
neighbor 10.10.110.1 peer group VTEP_GROUP
|
|
neighbor 10.10.110.1 remote-as 65101
|
|
neighbor 10.10.110.1 update-source Loopback0
|
|
neighbor VTEP_GROUP peer group
|
|
neighbor VTEP_GROUP ebgp-multihop 5
|
|
neighbor VTEP_GROUP send-community extended
|
|

|
|

|
|
neighbor 10.10.110.1 activate
|
|
!
|
|
address-family ipv4
|
|
no neighbor 10.10.110.1 activate
|
|
redistribute connected route-map RMAP_VTEP
|
|
```
|
|
|
|
To check peer status :
|
|
|
|
```cli
|
|
show bgp summary
|
|
