1... Who knows what to do? In order to save money for the customer, this time we didn't use smart routing devices embedded with carrier address blocks. We used a common fw and pasted 8 pages of a4 static route entries... Dizzy)

2. the technical application innovation in this case is to use vrrp-based virtual addresses for nat in the form of poor edge dashboard. Please know why-seamless nat switching );

4. The layer-2 stp should attract more attention and applications;

5. If the operator has two physical lines or two carrier lines with one wall, the problem will be simplified;

To add, the "L2/L3 hybrid design" may be reflected in the comprehensive use of tag/untag native/pvid SVI.
