[c-nsp] simple redunancy..

[Roy Blamski]

so something like this:

        ISP
/30           /30
 |               |
3750------3750
  |             |
  ---2851----


all devices are connected via ospf (over an internal network range)
and the links between the 2851 and 3750s are trunked.  the ISP is
routing us a /24

my dilemma:  how to keep a VPN connection up (GRE/IPSEC) that
terminates into the 2851, onto an address in the public /24, when we
lose one of the ISP connections.  it seems like i want to bridge
together the public vlan to each 3750...is that doable?  there are
other rfc1918 vlans shared between the 3750s and 2851 as well.

thanks for any help...
