ok, after reading my own post I think went off too far in left field......
before any posts show up on this one let me modify it somewhat.
Obviously if the point of entry to the network fails, the user has to
reconnect somewhere else.
The problem is more like - the 5300 is the access point, probably in bldg A.
The user community connecting is in bldg B.
Between the bldgs are redundant links through HRSP.
If an intra-bldg link goes down it is said that the L2F tunnel will fail
since HSRP operates at layer 3, the tunnel will not automatically be
re-established on the standby router.
So I think the challenge is re-establishment of the tunnel after a HSRP
router fails without the user having to disconnect and get his VPN through
the remaining router.
Anyone have any experience or thoughts with that kind of scenario?
