This text field holds the canonical name of the tunnel interface that traffic matching a specific address-family-agnostic (both IPv4 and IPv6 capable) CIDR route is forwarded through, the current, non-deprecated counterpart to the older jnxIpCidrRouteTunnelName. An administrator reads this when investigating how a particular route is actually being forwarded, to confirm traffic for that destination is indeed being routed into the expected tunnel rather than a plain physical interface. For example, this field might contain a value like "lt-0/0/0.1", identifying the specific logical tunnel interface carrying traffic destined for that route's prefix.
