if a LSP fails to forward data the MPLS control plane responsible for ISP select this error

The main function of MPLS forwarding plane can add labels or delete labels from an IP packet and forward the received packets

After an IP packet enters the MPLS network, the ingress LER will analyze IP packet and add proper to the packet

MPLS can use Ping or Trace route to detect LSP errors and locate faulty nodes

The master in the VRRP group is selected based on priorities

The master sends gratuitous ARP packets and notifies the connected device or host of its virtual MAC address 'iSSi

if the master fails the new master is selected among backup devices based on priorities

The priority ranges from 1to 255 When the backup received VRRP Advertisement packets which the priority is 0 the backup discards the packets
