EVPN-VXLAN : simplicité Juniper
Juniper est réputé for its simplicité EVPN-VXLAN vs Cisco. Exemple config spine-leaf :
- Commit-based : rollback atomique en cas d'erreur
- Apply-groups : templates réutilisables for leaf
- EVPN BGP underlay eBGP or iBGP with RR
- Anycast gateway sur chaque leaf (vs centralized sur Cisco)
- Support IPv6 EVPN natif
