Inter-cluster BLF over SIP Trunk
Recently we have configured Intra-Cluster BLF and now lets configure Inter-Cluster BLF so that we can monitor a device in remote cluster.
To configure this, we need to follow the below.
(Assuming that Partition, CSS, Route Pattern, Device Pool, Region, Location and other necessary parameters are configured.)
