I was playing with reverse routing and noticed the following behaviors

1)it can't deal with permit ip any any? Exact From subnet --> To subnet required

2)the created static routes are not the same as usual static routes? see below





HUB1 and HUB2 are connected and talking RIP.

Dynamic tunnel terminates on HUB1

I do a ping from SPOKE_IP to a loopback LOO on HUB2

thus traffic goes via SPOKE to HUB1 to HUB2

I see that a static route is created on HUB1. The route is redistributed in RIP and available on HUB2.

But from HUB1 I can't ping SPOKE_IP while it is possible via HUB2 which passes HUB2

Hi Davy,

1.) You can't use "permit ip any any" as the ACL for reverse route creation. That is simply too unspecific and can't be used as a template to generate routes in your routing table. Note that the reverse-route uses the destination part in the crypto map's ACL to generate routes into the routing table.

2.) I do not quite understand the description of your topology and router inerconnections. Is it possible for you to post the entire configurations of all three routers?

Best regards,
