Hi, I am designing an "Internet Building" concept using ethernet. Below is a model using 2 cisco Catalyst 1912's (12 port ethernet switch) and a cisco 2501. Switch 2 is on the 2nd floor and Switch 1 is in 1st floor. Does this look like a viable topology? Are there other/better ways to approach this for scaleability? Thanks for any ideas/experiences. x.x.x.0 /26 (Customer 2nd floor) | | x.x.x.64 /26 (Customer 2nd floor) | | | | Switch 2 (2nd floor) A | B | C VLAN 1 = A+C | VLAN 2 = B+C | | | (cable drop between 1st and 2nd floor) | | | Switch 1 (first floor) A | B | C VLAN 1 = B + C | | cisco (first floor) ip secondary x.x.x.0 /26 ip secondary x.x.x.64 /26 | | | T1 to Internet | |
