Cumulus Linux 2.5 – MLAG
cumulusnetworks.com 11
§ MLAG § Dual-Attached solutions for
capacity/redundancy § Simple migration path for existing
L2 solutions § Operational consistency with
scaled-out IP Fabrics
§ How? § Implemented via clagd &
associated commands § Bonding provides multi-pathing § Leverage existing LACP protocol
• LACP is easy to diagnose

Cumulus Linux 2.5 – VRR
cumulusnetworks.com 12
§ Virtual Router Redundancy: § Provides default gateway
redundancy (vIP) § Protocol-free redundancy
mechanism • It is not VRRP, it is VRR!
§ Active-active FHRP § Enhancements in CL2.5
• Supports Router Redundancy beyond host connectivity
• Integration with ifupdown2

Cumulus Linux 2.5 – VLAN Scale
cumulusnetworks.com 13
§ VLAN-aware Bridges § New 802.1Q Linux bridge
driver § Enables VLAN Scale
• VLAN-aware bridge scales to 2000 VLANs
§ Single instance spanning tree • Supports STP, RSTP
§ Ifupdown2 Configuration § Migration path: mixed mode
support • Recommended for migration only
Bridge 100 Bridge
VLAN-aware Per-VLAN
VLAN 100 VLAN 1-10, 100, 200

Cumulus Linux 2.5 – LACP Bypass
cumulusnetworks.com 15
§ LACP fallback mechanism § Use Case: PXE boot for host
connected to switch via LACP
§ Bypasses LACP protocol negotiation
• LACP negotiation takes over when LACP partner is detected
