I am now working In a setup below
2-7206VXR routers for Redundancy.connectivity as follows
2-7206 each have redundancy to 2-6506 switch and these two switches have
redundancy to 2 WAN routers. simply the setup is as follows.
7206 \/ 6506 \/ Wan ROUTer----ISP
7206 /\ 6506 /\ Wan Router----ISP
more than 500 sites through MPLS it is connecting to HUB ( 1841 routers)
All spoke location routers are ipsec enabled IOS
I am in need of configuring DMVPN in the central site so that there is no
need for me to add any configuration in the central site if any new spoke locations
comes up.I have gone through many documents in the cisco site for the same and i have configured the same.
But for my surprise nothing is working ( i.e the packets are not getting encrypted
and so on......) and how to sync the HSRP and ipsec.
I am not confident which ip must
Sample IP configuration
HSRP ip for 7206VXR is 172.21.30.5
Wan router ip 192.168.1.2 ( as of now one WAN router is active )
I need configuration for both central site and the branches ( i.e it is tested in the live environment
and it is working fine).I am not sure that what must be the ip address
to give in the isamkmp key exchange ( i.e whether WAN or 7206 router's ) in Spoke locations.
I am running short of time, help me if you can
