Doing a bridge on the 2851 is an option, but if the 3750's are part of a single stack, then just use a multi-chassis etherchannel.
Otherwise, put up /31's between the 3750's and 2851; at that point, either terminate connectivity on a loopback, or use two tunnels for each of the ISP's (in separate VRF's on the 2851) and let your IGP deal with it. ----- Original Message ---- From: Roy Blamski <[EMAIL PROTECTED]> To: [email protected] Sent: Monday, December 17, 2007 10:14:15 AM Subject: [c-nsp] simple redunancy.. 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... _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
