Hello
I have a network with some providers like
VSAT, LEASED LINE,DialUp and so on,,
so..
I have now a tunnel interface for connecting my branch office to my central office..
so I am looking for a better solution instead of tunnel interface..

Depends I guess on how often you passing data across that branch office connection. If it is not ofter used then maybe Frame Relay CKT, If it is often used them maybe just go with a T1 of sort.
I imagine when you say tunnel you are refering to VPN tunnel right.
Hope this helps

It should be determine by yourself w/ your requirement (bandwidth, QoS, type of traffic, etc.), budget and cost/benefit, etc.
It is hardly to tell what is suitable for you.
Please explain more then we can suggest.
Hope this helps.

Hi
acctualy I have a Vsat connection between my remote site and central office
on both site we have router and sat modem
I have now a tunnel interface between my two routers,I am looking for a better idea,,

What I suggest if you can source a stable and cost-effective solution then it will be the choice. The VSAT should not be cheap and very stable.
For the tunnel interface, it really depends on your usage. Can you advise why you require tunnel and what traffic will be tunnelled ?
If the link is not a private connection then you may require tunnel, if it is a point-to-point private link then tunnel may not be required. Moreover, tunnel will utilize CPU resource more, but only two tunnel should be fine.
Hope this helps.

hello
we have to use Vsat, because this is for backup link..
here is the configuration of my tunnel..
interface tunnel71
bandwidht 1000
ip address 172.19.1.40 255.255.255.0
no ip redirects
ip mtu 1400
ip nhrp authentication mamfnhrp
ip nhrp map 172.19.1.1 10.234.117.116
ip nhrp map multicast 10.34.117.116
ip nhrp network-id 771
ip nhrp holdtime 300
ip nhrp nhs 172.19.1.1
delay 1000
tunnel source vlan1
tunnel mode gre multipoint
tunnel key 7771
**************
do you have a better idea? or a better instead of this?

What I only concern is the MTU size. Will it affect the traffic and match w/ the hosts at LAN side.
As I mentioned before, if there is more cost-effective solution (I mean physical media) then you can consider it. If for the tunnel interface, I have the above comment only.
Did I ans. your question ?

That is a very interesting tunnel. Mutlipoint GRE using nexthop is commonly used over MPLS when you need to encrypt the traffic but still allow for any to any connectivity.
If I read your question correctly you are asking if you can send the traffic over the VSAT without putting it in the tunnel. To make that work your provider would have to have the routes between your sites in their network. If this is a managed network then they may do it.
The other issue is that you are running multicast.. or at least you have it defined on your tunnel. This is a common reason to run tunnels. Although you can now run multicast over MPLS it is not a common offering yet. Again if your provider offers it you can do it.
The main advantage to a tunnel is that you can make changes to your network and not tell your provider anything. If you run without a tunnel they now have routers that are now participating in your network and you must corrodinate with them.
