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 trac to correct VLT node when the control trac reaches wrong VLT node due to hashing at the VLT
LAG level on the ToR.
• Routing the data trac which is destined to peer VLT node.
• Synchronizing the neighbor entries learned on VLT VLAN interfaces between VLT primary and secondary node.
• Synchronizing the IP address of VLT VLAN interfaces between the VLT primary node and secondary node.
• Performing routing on behalf of peer VLT nodes for a congured time period when a peer VLT node goes down.
When you congure Layer 3 VLT peer routing by using the peer-routing command in VLT DOMAIN mode, it applies for both IPv4 and
IPv6 trac in VLT domains. Layer 3 VLT provides a higher resiliency at the Layer 3 forwarding level. Routed VLT enables you to
replace VRRP with routed VLT to route the trac from Layer 2 access nodes. With neighbor discovery (ND) synchronization, both
the VLT nodes will perform Layer 3 forwarding on behalf of each other.
