IPIP Tunnel:
However, we have questions about this. Do the "Down" tunnels still consume resources on the GER? Is there cause for concern?
Check the memory Utilization by the below command:
No impact on Memory utilization seen on RE Memory by MPLSoUDP tunnels which are down. No next-hop details are pushed to line cards either so there is no impact on line card memory
Routing-engine Memory Utlization, no impact seen.
