Hi,
I have the following configuration but I can't ping to tunnel from one spoke router to hub router and vice versa. I have the static ip on HUB fa0/1 interface and dhcp ip on spoke router. Does dhcp plays any role in disfunction of this one.
HUB:
interface Tunnel12
ip address 172.28.18.1 255.255.255.0
no ip redirects
ip mtu 1436
ip nhrp map multicast dynamic
ip nhrp network-id 11386
tunnel source fa0/1
tunnel mode gre multipoint
tunnel key 111386
SPOKE: (dhcp private ip)
interface Tunnel12
ip address 172.28.18.19 255.255.255.0
no ip redirects
ip mtu 1436
ip nhrp map multicast x.x.x.x
ip nhrp map 172.28.18.1 x.x.x.x
ip nhrp network-id 11386
ip nhrp nhs 172.28.18.1
tunnel source FastEthernet0/0
tunnel mode gre multipoint
tunnel key 111386
Regards,
