Router Clustering!

Hi,

As we know the Cisco PIX/ASA firewalls have the stateful failover feature.Which allow the active the vpn ,http sessions being up during the failover.

I am interested in whether Cisco Routers have the similar feature? . Can i keep the active vpn, nat sessions on different router through the clustering or somehow redundancy.

p.s. Please don't offer the HSRP ;). It is just for redundancy of L3 connections.I need the stateful redundancy

thanks

Re: Router Clustering!

Hi Leo,

Here 's a link for stateful failover :

http://cisco.com/en/US/products/ps6350/products_configuration_guide_chapter09186a0080455b64.html

But u dont want the HSRP :-(

Even for nat we have the same process :

http://cisco.com/en/US/products/sw/iosswrel/ps1839/products_feature_guide09186a008060c61d.html

This document says that tables are replicated

But I think it is similar to ASA while duplication http relication and all the steful information to the standby device

Are u looking for failover interface or something like SLA monitor?

Re: Router Clustering!

Hi Raj,

Very good link for stateful vpn! Should be tested!

No i didn't want HSRP, because of its purpose. As i needed not just redundancy, i asked not to suggest the HSRP. But conjunction HSRP with SSO seems to be solution for me.

thanks

Re: Router Clustering!

Hi,

I have Cisco 7204 VXR with NPE-400, and advanced ip services.

As i understood if i want to make Stateful Failover for IPSec, the only requirments for second box is advanced ip services IOS? that is all.

Re: Router Clustering!

Hi Raj,

In this case i think the only requirements is having the same IOS,no matter which kind of boxes you gonna use.

Correct me, if i am wrong
