Hello,
Just browsing the site, came across this.
Yes you can use DLSw HSRP configuration.
We have used this type of configuration for some time now.
typical config - Router A and B at one site (NETWORKA). Router C and D at another (NETWORKB).
Leave Loopback 0 interfaces as a failsafe option - if problems arise or if using STUN tunnelling. I tried using HSRP on this and I expect due to cabling issues, it maybe a good idea to leave this connectivity to Loopback interfaces.
Apply this to both routers at either end, substitute IP addresses and interfaces appropriate to your IP addressing conventions.
You can apply this to any interface, whether Ethernet / FastEtthernet, Token, VLAN. We use a combination, but all seem to work fine.
On router A
dlsw local-peer peer-id 10.1.1.3 (local HSRP address of router A & B)
dlsw remote-peer 0 tcp 20.1.1.3 (remote HSRP address of Router C & D)
int VLAN 100
ip address 10.1.1.1 255.255.255.0
standby 100 priority 105 preempt
standby 100 authentication NETWORKA
standby 100 ip 10.1.1.3
!
On Router B
dlsw local-peer peer-id 10.1.1.3 (local HSRP address of router A & B)
dlsw remote-peer 0 tcp 20.1.1.3 (remote HSRP address of Router C & D)
int VLAN 100
ip address 10.1.1.2 255.255.255.0
standby 100 priority 100 preempt
standby 100 authentication NETWORKA
standby 100 ip 10.1.1.3
!
On Router C
dlsw local-peer peer-id 20.1.1.3 (local HSRP address of router C & D)
dlsw remote-peer 0 tcp 10.1.1.3 (remote HSRP address of Router A & B)
int VLAN 200
ip address 20.1.1.1 255.255.255.0
standby 200 priority 105 preempt
standby 200 authentication NETWORKB
standby 200 ip 20.1.1.3
!
On Router D
dlsw local-peer peer-id 20.1.1.3 (local HSRP address of router C & D)
dlsw remote-peer 0 tcp 10.1.1.3 (remote HSRP address of Router A & B)
int VLAN 200
ip address 20.1.1.2 255.255.255.0
standby 200 priority 100 preempt
standby 200 authentication NETWORKB
standby 200 ip 20.1.1.3

Note Higher Priority interface is the PRIMARY router of the two being used in HSRP mode, i.e in this case Routers A and C in each network.
Hope this helps.
