Hello Cisco, I'm trying to figure out why my ISP adds this static route to an internal address to my routing table. I was able to determine that it is very important by adding an ACL to block outbound traffic to it. Is it just some ISP magic?
Thank you in advance for any assistance!
ip address dhcp
ip nat outside
184.108.40.206/24 is subnetted, 1 subnets
C <omitted> is directly connected, FastEthernet4
172.19.0.0/32 is subnetted, 1 subnets
S 172.19.41.19 [254/0] via 220.127.116.11, FastEthernet4
I am guessing that the address 172.19.41.19 is some kind of management or monitoring station in the provider network. I have seen some situations like this where the provider has management and/or monitoring stations that want to track the public address but the devices are in private address space within the provider network. I would suggest that you ask the provider about the address and about the impact if you block it. I have had the situation a couple of times where the customer did block the extra address and it did have a negative effect on their network connectivity.
