I am configuring NAT in stick configuration. I am not comfortable with the logic behind this. Also,I have completely gone thru the CISCO document describing the NAT in stick configuration. Still i donot understand
Below I am explaining the issue
Please find the attached Topology diagram and configuration. Please correct the what i am missing in the configuration.
1. I am not able to ping 220.127.116.11 (INTERNET Router) IP address from PC Router.
2. What is the need of PBR configuration here.
3. In what logic i have to make the interface as INSIDE or OUTSIDE. (Since in this case we are configuring public ip address and private ip address in the same eth 0/0 interface and creating loopback 0 interface)
I believe i have explained the need to your understanding. Please help
Thanks in advance
Thank you for your kind words.
While the Cisco does not explicitely state that the NVI can be used for the NAT-on-stick applications, it does not say neither that it can not be used. In the command reference for 12.4 IOS, it is stated that the "vrf" option in the "ip nat source" command is optional, thereby allowing its use also in the global routing table.
Regarding that the NVI is allegedly supposed to provide means for communication between different VRFs, this is a quotation from the article about the NVI posted earlier here:
NVI is not a new way of doing NAT; it's a new feature to resolve NAT restriction.
And this is what I also think about NVI. Not primarily VRF-specific stuff (even though it might in cases help solve some problem but I do not know enough about such applications) but rather a different approach to do NAT.
