In a scenario, there are three devices R_A, R_B, R_C and connected as shown in diagram, topology

How can implement that Link 1 and Link 2 work in active and standby mode i.e. Link 2 will be active if Link 1 get fail other Link 2 on standby where Link 3 active all time with use of auto cost single IGP process and vrrp at all devices.

  • How does a layer-3 link relate to VRRP, which is a protocol for fooling devices connected at layer-2? Equal cost links will be load balanced. You may be able to do something with AD to keep the routes on one link at a higher AD than on the other.

You could achieve this using ospf between R_A and R_B and give the link 1 lower metric
