I currently have a 3560 with the following setup:
Switch:
GigabitEthernet0/1
description to_fw
no switchport
ip address 1.2.3.2 255.255.255.252
no cdp enable
!
int Vlan10
ip address 2.2.2.1 255.255.255.0
!
int Vlan20
ip address 3.3.3.1 255.255.255.0
!
ip route 0.0.0.0 0.0.0.0 1.2.3.1
!
Firewall:
A L3 interface 1.2.3.1/30, with routes for 2.2.2.0/24 and 1.2.3.0/24 pointing to 1.2.3.2.
A very simple setup that works very well for what we do. We are replacing the 3560 with a pair of 3850s. My original plan was to run HSRP on the L3 VLAN SVIs and on the routed interface, setup STP, portchannels, etc, and move on with life...however the 3850s do not currently support HSRP.
That's right, HSRP that has been around since 1998 (or so) isn't in the current IOS for the 3850.
I cannot seem to find a way to virtualize the IP of the VLANs (gateways for their vlan members) and the routed interface IP (gateway from firewall and for traffic from the switch). HSRP, VRRP, GBLP, all seem to not be part of the IOS on the 3850. IPSERVICES doesn't seem to have these features either, not that it would be a viable option for me.
What options do I have? I have to be able to define an IP as a gateway that I can define on my clients that will float between switches. With HSRP and interface tracking the solution is simple.
Thanks.
