[c-nsp] GRE Tunnels to HSRP virtual IP?

[Eric Helm]

Hello,
Can a GRE tunnel be established to the virtual IP in an HSRP group?
If so, is the 'tunnel source' command the only thing needed on the HSRP
side to get it to work? Obviously, I haven't got it working correctly,
or I wouldn't have posted. Both sides of the tunnel interface show
'Tunnel100 is up, line protocol is up', however I can't get traffic to
go across the tunnel.

Config snip for both sides:
interface Tunnel100
 ip address 192.0.0.XXX 255.255.255.252
 ip mtu 1500
 tunnel source XXX.XXX.XXX.YYY
 tunnel destination XXX.XXX.XXX.XXX

If I configure the tunnel to the actual IP assigned to the interface on
the HSRP router, it works fine. Essentially, what I am needing is a VPN
from the remote side to the HSRP router(s). If I need to configure 2
tunnels, one to each routers actual IP, what is the best method to
handle the routing to the remote subnet?

Thanks,
Eric
