Layer 2 implementation

OVHcloud connect diagram - step 2

The L2 tunnel is forwarded directly to/from the vRack, so all L2 traffic is forwarded to/from the customer interconnection.

L2 traffic refers to Ethernet frames, with an 802.1q header, if applicable:

  • Ethernet broadcast is forwarded.
  • Unknown Ethernet unicast is forwarded.
  • Multicast is forwarded (considered broadcast, limited to 20 pps).
  • Specific point-to-point Ethernet frames (like LLDP or LACP) are not forwarded

Only one OVHcloud Connect L2 is supported per vRack: each PoP/EntryPoint can only be associated with one DC/EndPoint.

With L2 mode, redundancy cannot be exploited between two PoPs/EntryPoints. The only solution is to use a LAG on a PoP/EntryPoint.

 

Connection mode details

L2 operates at the Ethernet level. The customer’s vRack is extended “as-is” from OVHcloud and forwarded to the customer link. Transparent to VLANs, this mode is the best way to interconnect the customer’s legacy network with an OVHcloud vRack.

The L2 mode is limited to a point-to-point topology: a backup link through a second PoP is not supported.

LACP is mandatory for aggregation when two links are configured with PoP.

Jumbo frames up to 9,000 bytes are supported.

Connections between a PoP and a DC benefit from the OVHcloud backbone. An internal link failure is therefore supported and will not impact customer traffic.
