Symptom
Very high output rate seen on Tunnel interface.
R1(config)#do sh int tunn 100 | in rate
Queueing strategy: fifo
5 minute input rate 1000 bits/sec, 1 packets/sec
5 minute output rate 16860000 bits/sec, 1931 packets/sec
A lot of Netflow template packets are sent just after HSL is enabled.
Conditions
HSL is enabled and traffic is sent through a Tunnel interface which uses a Multilink interface as source interface.
This is just seen on routers with Multilink interfaces. The same configuration with Ethernet interfaces works fine.
