asa and isp failover

mialbert

Have two asa's and two isp's.  does cisco have another dual isp failover solution for the asa except bgp.  Have a number of servers behind the asa and alot of inbound translations to those servers.  Would rather not re-ip those and have to get a class c etc... Am wondering if installing dyndns on all of the servers would be a good solution

Hello,

What about Ip SLA, that would be the only one .

Yes, i'm aware of ip sla.  What i was wondering about was solving the problem of dns resolution for the inbound servers.  The servers will need to be aware of the failover to the second isp in some way.  Bgp will distribute the class C space between the two isp's.  Aggregators will host dns for all domains.  Didn't want to do those two solutions for various reasons.  A third option will be to do dyndns on the servers locally.  That way, when the isp fail's over the dyn dns agent should discover the change and route out to the new isp.  Was wondering about this solution and if cisco may have another recommended way, besides bgp.
