Ring ID: the range is from 1 to 255.
Troubleshooting FRRP
To troubleshoot FRRP, use the following information.
Conguration Checks
• Each Control Ring must use a unique VLAN ID.
• Only two interfaces on a switch can be Members of the same control VLAN.
• There can be only one Master node for any FRRP group.
• You can congure FRRP on Layer 2 interfaces only.
• Spanning Tree (if you enable it globally) must be disabled on both Primary and Secondary interfaces when you enable FRRP.
– When the interface ceases to be a part of any FRRP process, if you enable Spanning Tree globally, also enable it explicitly for the
interface.
• The maximum number of rings allowed on a chassis is 255.
Sample Conguration and Topology
The following example shows a basic FRRP topology.
Example of R1 MASTER
Example of R2 TRANSIT
Example of R3 TRANSIT
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 congure 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 conguration connects VLT devices across Data Centers using FRRP; however, the VLTi may or may not participate
as a ring interface of any FRRP ring.
