顧客には重複する IP を持つ 2 つのブランチ サイロがあります。重複を回避するためにサイトとサーバー間の通信を確立するには、データ ポリシーをどのように構成する必要がありますか?
正解:A
When dealing with overlapping IP addresses in different branch sites, it's crucial to use NAT (Network Address Translation) to avoid IP conflicts and establish proper communication.
* NAT Configuration:
* Source NAT: This involves translating the source IP addresses of the packets as they leave a specific interface. This can help avoid IP conflicts by ensuring that the IP addresses used within the network are unique.
* Data Policy: A data policy must be created that matches the source IP addresses and applies the NAT pool to translate these addresses.
* Option A Analysis:
* Policy Definition: The data policy Srvc_Plane_NAT includes a sequence that matches the source IP 10.0.0.1/32 and accepts the action to apply NAT using nat pool 1.
* Interface Configuration: The interface ge0/0/0 is configured with the IP address 192.168.1.1/32 and is not shut down, ensuring it is active and can handle the NAT translation.
