Hello,
What do you mean by "if the routing happen to messed up" ? If you
have an IGP on your WAN and LAN side, and a failure occurs, here is
what should happen:
If a LAN failure occurs on R1, HSRP will fail over. Routers on the
WAN side will only see a path to the LAN via your IGP thru R2.
If a WAN failure occurs on R1, R2 again will be the only path to the
LAN network in your IGP. As far as HSRP goes, you can configure HSRP
to fail over when the WAN link fails on R1. If not, R1 will send an
ICMP redirect (depending on IOS) saying R2 is the better gateway since
R1 can only reach the WAN via R2.
Hope this helps.
