I have cisco router 2901 ios used 15.3 m1 the issue the lan interface on router out icmp to all my privet network and the internet go slow and down
Hi,
Could you please brief the issue with more explanation , what is happening and at what time are you facing the issue , Like when some specific traffic is running in network or something else.
and you have written LAN interface in router sends imp to out to private network ( Is that causing the issue and how you are sure).
Have you checked the cpu utilisation of router , interface stats of lan and wan ( Any errors are pilling ).
Please check for some basic investigation and logs for more help.
Hope it Helps..
