I have a site to site vpn GRE tunnel from a 2811 router to a 2811 router.
On the remote site I have 2 routers configured with HSRP. The only way I've founded for the tunnel to work with HSRP is to configure one different tunnel on each router. But both of them are always up.
Could anybody tell me what is the bandwidth consumed by a tunnel only being up, without traffic?
Thanks in advance
