Hi guys,
i have a cisco 1811 router (spoke) with 2 DSL connecions from my provider he is using DMVPN to connect to a 2811 (Hub).
My question is how could i share (load balacing) my traffic using both DSL connections ?

Hello Jawad,
or you use multilink PPP over ATM to make use of both DSL (this requires cooperation with DSL provider).
or you need to use two mGRE tunnels on both ends again if this is provided by the service provider it requires its intervention.
But to do this also the hub router needs two WAN links to be able to support two mGRE tunnels (this is my idea I may be wrong on this)
Hope to help

both DSL are PPPoE and i dont think the provider is wiiling to help me with anything..
the way it s working now is fallback, that means if the DSL1 is down automatically DMVPN brings another tunnel over the DSL2.
Also the Hub router is configured with 2 IP on his WAN port.
thanks for help

Hello Jawad,
>> Also the Hub router is configured with 2 IP on his WAN port.
so the second option is possible:
you need to have two mGRE on the remote with equal parameters and you will have load balancing
and two mGRE on the Hub too
Hope to help

Hi
i already have 2 tunnels with equals like this:
interface Tunnel1
bandwidth 1000
ip address 11.0.0.2 255.255.255.0
ip mtu 1400
ip nhrp authentication cisco
ip nhrp map 11.0.0.1 x.x.104.7
ip nhrp map multicast x.x.104.7
ip nhrp network-id 111
ip nhrp holdtime 450
ip nhrp nhs 11.0.0.1
ip tcp adjust-mss 1360
delay 1000
tunnel source Dialer1
tunnel destination x.x.104.7
tunnel key 111
tunnel protection ipsec profile profile
!
interface Tunnel2
bandwidth 1000
ip address 12.0.0.2 255.255.255.0
ip mtu 1400
ip nhrp authentication cisco
ip nhrp map multicast x.x.104.8
ip nhrp map 12.0.0.1 x.x.104.8
ip nhrp network-id 112
ip nhrp holdtime 450
ip nhrp nhs 12.0.0.1
ip tcp adjust-mss 1360
delay 1000
tunnel source Dialer0
tunnel destination x.x.104.8
tunnel key 112
tunnel protection ipsec profile profile
is that what you mean by two mGRE or something else ? or should i add some specific command to the 2 tunnels ?
Thanks

Hello Jawad,
this is near to what I was thinking you should be able to use both if you run a routing protocol over the two mGRE tunnels using the same parameters
What routing protocol are using over the two mGREs ?
EIGRP, OSPF ?
Hope to help
