IPv6 Peer Routing in VLT Domains Overview
Peer routing for IPv6 packets in VLT domains is supported on the S4810, S4820T, S6000, Z9000, and MXL platforms.
Virtual Link Trunking (VLT) is a mechanism that enables the physical links between two devices that are called VLT nodes or peers, and
within a VLT domain, to be considered as a single logical link to external devices that are connected using LAG bundles to both the VLT
peers. This capability enables redundancy without the implementation of Spanning Tree Protocol (STP), thereby providing a loop-free
network with optimal bandwidth utilization.
Peer routing for IPv6 packets in a VLT domain is supported. This mechanism of IPv6 peer routing is supported on all the platforms that are
compatible with IPv6 routing and support VLT. This functionality performs the following operations:
• Forwarding the control traffic to correct VLT node when the control traffic reaches wrong VLT node due to hashing at the VLT LAG
level on the ToR.
• Routing the data traffic which is destined to peer VLT node.
