DMVPN Hub on HSRP standby router

I was wondering if a DMVPN Hub was able to provide redundancy on an HSRP standby router.

I currently have an active tunnel to the standby, but am unable to update EIGRP..

Thank You in adavnce..

Re: DMVPN Hub on HSRP standby router

Check GRE keepalives is enabled or not, if enabled remove that, then check the routing updates.

Check whether you allowed ESP, UDP 500, UDP 4500 and GRE on your access-list.

Also Adjust the MTU size, using the cmd ?ip tcp adjust-mss 1360?
