Refer to the exhibit. The figure shows a service provider network that has MPLS TE tunnels that originate from GSR1, GSR2, and GSR3. While GSR1 and GSR2 have multiple paths to the core network, the GSR3 has a single path into the core. For GSR1 and GSR2, the purple links are the preferred paths, but because they are multihomed to the core, they can also take the black, less- desirable path. The less-desirable black paths need to be retained for certain operational reasons. GSR3 has a single path into the core network, and a TE tunnel originating from GSR3 must be able to use this path. It has been noted that if the network encounters multiple link failures or link transitions, the TE tunnels originating from GSR1 or GSR2 can preempt the TE tunnel originating from GSR3, thus causing a lack of MPLS connectivity. The operations team does not want the TE tunnel originating from GSR3 to be preempted unless this tunnel is administratively shut down. How should this situation be mitigated?
