Hello, I inherited a Cisco 2611 that I have been trying to clean up and understand the config on.
For a while I have been wondering why the following were being specifically blocked...
access-list 110 deny 53 any any access-list 110 deny 55 any any access-list 110 deny 77 any any access-list 110 deny pim any any
I was doing some reading trying to learn about PIM and found this link which references a DOS vuln.
http://securecomputing.stanford.edu/alerts/cisco-update-17jul2003.html
Was this a way to circumvent the listed vuln.? the doc references IOS below 12.3, as I am now above that - may I safely remove these denys?
Thanks
