What the heck does the "redundancy HSRP" part of this command mean?
ip nat inside source static 192.168.5.33 220.127.116.11 redundancy HSRP1
I am trying to get a full appreciation for the challenges of running NAT in a redundant environment, such as with HSRP, and I saw the following cryptic statement on a Cisco web page:
When an Address Resolution Protocol (ARP) query is triggered for an address that is configured with Network Address Translation (NAT) static mapping and owned by the router, NAT responds with the BIA MAC address on the interface to which the ARP is pointing. Two routers are acting as HSRP active and standby. Their NAT inside interfaces must be enabled and configured to belong to a group.
Maybe its just me and Im being dense today, but this paragraph seems convoluted. An example to show what they mean would have been nice.
Cisco has some great white paprers and some outstanding explanations for different technologies, but it seems that the white papers for SNAT and NAT with HSRP are not one of them.Maybe its because the technology is relatively new. I also hate it when the grammar is poor and there are egregious punctuation erros in a document. It makes it difficult to read.
Anyway, can anyone clear the cloud from my brain? I mean as far as this is concerned. It would take God and his sister to clear ALL the fog from my head! LOL
