HSRP

I have a pair of 2600 routers ... Each has two Ethernet ports, and no more can be added. On each router, 1 Ethernet port is used for internet, and the other to the internal LAN switch. I would like to implement HSRP, but do not have an available Ethernet port. Can I do HSRP via the Ethernet connection going through the LAN switch?

HSRP should be implemented with the two internal ethernet interfaces you have available.

So what you need to do is the following:
rtr A
int eth0/1
 ip address 192.168.223.2
 standby 1 priority 105
 standby 1 preempt
 standby 1 ip 192.168.223.1
 
rtr B
int eth0/1
 ip address 192.168.223.3
 standby 1 preempt
 standby 1 ip 192.168.223.1


So now the ip address 192.168.223.1 is the gateway address that will be in use on one of the routers.  so rtr A is the primary rtr since his priority is 105  - 100 is the default.  If rtr A goes down or rtr A's ethernet connection goes down, rtr B will take over acting as 192.168.223.1.  You can also do more with this such as track other interfaces for that their state and adjust the priority value as well.

So with HSRP like this, this is for failover only, it will not be redundant.
