My colocation provider has setup HSRP for us and has provided us 2 drops (plugged into 1/1/1 and 1/1/2) from their routers as well as a /29 with 2 HSRP IP's and the rest of the /29 usable for the switch.
I know that HSRP should be pretty much plug and play as long as the ports are in the same VLAN.
However I'm confused as to how to the IP setup should work.
Currently I've assigned port 1/1/1 the full /29 however I think this is incorrect because if I were to unplug it port 1/1/2 wouldn't work as it has no IP assignment.
What's the proper way to do this?
Here's how it works:
112.168/29 - NETWORK ADDRESS
112.170 - Virtual HSRP Address
112.171 - Colo Router A
112.172 - Colo Router B
Then you have options:
Terminate the connections into the same VLAN, and then put your devices right into that VLAN and give them public addresses, with 172-174 being usable.
OR
Terminate the connections into the same VLAN, and connect either a router or a firewall into that same VLAN, which would have a .172-174 address to provide routing, NAT, and security for privately addressed devices behind it.
