FRRP Support on VLT
Using FRRP rings, you can inter-connect VLT domains across data centers.
These FRRP rings make use of Layer2 VLANs that spawn across Data Centers and provide resiliency by detecting node or link level failures.
You can congure a simple FRRP ring that connects a VLT device in one data center to a VLT devices in two or more Data Centers.
NOTE
: This conguration connects VLT devices across Data Centers using FRRP; however, the VLTi may or may not participate
as a ring interface of any FRRP ring.
Following gure shows a simple FRRP ring inter-connecting VLT device:
