ICMP redirect, Dynamic IP Route generated on Servers
Here is my setup.
Local Ofice----> WAN Links---->Remote DC-> Firewall -----Internet link.
At Remote DC we have Windows systems, cisco switches/routers/VPN concentrator, AS400 systems, Checkpoint Firewall,
load balancers, Bluecoat proxy etc.
Sometime some of the devices at remote DC are not accessible. For example there is a client at local office with the IP 10.0.0.10 and remote server 184.108.40.206(remote DC) Sometimes from 10.0.0.10, I am unable to ping 220.127.116.11. The tracert to 18.104.22.168 reaches the routers of remote DC. During this time, I inspected the routing table on 22.214.171.124 and I found one route specific to 10.0.0.10 pointing to internet firewall as the path, which is wrong.
These symptoms are founf on Windows/AS400/Bluecoat devices.
How can I track the device which is injecting these routes? Is it because of ICMP redirect?
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
