IPv6 Peer Routing in VLT Domains Overview
VLT 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.
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 control traffic to the correct VLT node when the control traffic reaches the 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.
● Synchronizing neighbor entries learned on VLT VLAN interfaces between the primary and secondary node.
● Synchronizing the IP address of VLT VLAN interfaces between the VLT primary node and secondary node.
