Hello, I have to change a Cisco 3845 and install a Cisco ISR 4451. The problem is I have a subinterface with 30 helper-address: When I insert more than 16 directions using helper-address command, I have an error message which says that the router does not support more than 16 helper-address in an interface.
What can I do to solve it, without using another router? The IOS version that I have installed in the router is Fuji 16.8.2. I hope you could give me a piece of advice.
Possible software or licence limitation.
Thank you Paul.
I'm sorry, but I haven't found any information about it except that the maxium number of helper-address in an interface can be different depending on the router's model
here is the good thread for reference :
