Hi Roman,
To the best of my knowledge, MTU on the master tunnel interface is fixed.
The only potential issue I could see is for the traffic generating/desalinated from/on the routers themselves as the master tunnel interfaces are used on control plan...
Hello,
Any reason to change that? As my understanding is the master tunnel in CBTS is just a logical pointer rather the real data plane forwarding interface (the member tunnel is).
Thanks,
Hi there,
Below is the configuration guide for it.
