The Traditional Solution
The traditional solution is to use CAR to rate-limit ICMP to given destination(s), on all border interfaces.
- access 155 permit icmp any any
- int f0/0/0
- rate input acc 155 90000 64000 64000 conf tr exc dr
or
- access 155 permit icmp any 207.106.4.0 0.0.0.255
- int f0/0/0
- rate input acc 155 90000 64000 64000 conf tr exc dr
sho int rate shows you the progress...
