Always on

[Maverick8673]

I currently have one router connected via frame relay and a second router connected via cable, the frame relay is primary with the cable in a HSRP situation. Would there be a way to have the cable always on not in hsrp and there for seemless failover. Currently when the frame fails and the cable takes over, all my uses have to restart their RDP connections. I would like to have the cable there for them so that they wont see this interuption. Is there anyway to do this?

Questions:

How is the cable backup being done?
Via an IPSec tunnel? IPSec and GRE?
What routing protocol are you using?

What I'm trying to get at here, is if you have a GRE/IPSec tunnel established with a routing protocol, the routers will have 2 ways to a destination. If one of the routers failover (specifically the FR), then the second is removed from the routing table and your session would continue on failover router.

The cable is IPSec routing protocol is EIGRP. What I would like is to not have a HSRP configuration but to have both of these router running that way there is a seemless transistion from one to the other without the interruption that I seem to get with the HSRP in place.

HSRP usually does not cause an interruption in service.

What I would suggest:

1) Enable EIGRP on the FR router and cable router (if you haven't done so already).
2) Configure an IPSec tunnel between the cable router and the other end (which you've done already)
3) Configure a GRE tunnel between the cable router and the other end thru the IPSec tunnel (yes a tunnel within a tunnel).
4) Establish a EIGRP adjacency between the cable router and other end thru the GRE tunnel.
5) verify that EIGRP routing table is being populated into the cable router from both ther FR router and the other end.

At this point you might have to start manipulating routing metrics but that's not so hard to do (to have routes preferred one way).
