I would like to configure HSRP or VRRP between a Cisco1841 router and a Cisco871.  

I have three different scenarios:

Three networks on the same interface (using secondary addressing)

Three VLANs using subinterfaces on the Cisco1841

Three Networks - Two on the fa0/0 as primary/secondary, One on fa0/1.

-
So if the networks are

10.0.1.0/24
10.0.2.0/24
10.0.3.0/24

How would HSRP or VRRP be configured in these scenarios to have all traffic failover.  I understand there are some limitations to the 871 series.  I have advanced IP feature set on both.

On the same interface, create separate HSRP groups on the interface on each router for each IP range.

For example, on the 1841...

int vlan1
ip address 10.0.1.2 255.255.255.0
ip address 10.0.2.2 255.255.255.0 secondary
ip address 10.0.3.2 255.255.255.0 secondary
standby 1 ip 10.0.1.1
standby 2 ip 10.0.2.1
standby 3 ip 10.0.3.1
exit

and on the 871...

int vlan1
ip address 10.0.1.3 255.255.255.0
ip address 10.0.2.3 255.255.255.0 secondary
ip address 10.0.3.3 255.255.255.0 secondary
standby 1 ip 10.0.1.1
standby 2 ip 10.0.2.1
standby 3 ip 10.0.3.1
exit




Using sub-interfaces (1841)....

int fa0.1
ip address 10.0.1.2 255.255.255.0
standby 1 ip 10.0.1.1
exit
int fa0.2
ip address 10.0.2.2 255.255.255.0
standby 2 ip 10.0.2.1
exit
int fa0.3
ip address 10.0.3.2 255.255.255.0
standby 3 ip 10.0.3.1
exit

and on the 871...

int fa0.1
ip address 10.0.1.3 255.255.255.0
standby 1 ip 10.0.1.1
exit
int fa0.2
ip address 10.0.2.3 255.255.255.0
standby 2 ip 10.0.2.1
exit
int fa0.3
ip address 10.0.3.3 255.255.255.0
standby 3 ip 10.0.3.1
exit
