multilinking multiple interfaces
Dear,
i have one project where i need 10 Mbps date. local provider provides only 2 Mbps per Leased lines(local provider also providing LL on Ethernet interface). Total will be 5 Point to Point leased lines between Head office and branch office. where my branch will distribute bandwidth to different customers. i need to combine through put 10Mbps.
I have Catalyst 4506 in head office and 2950 in branch office to connect leased line. please advise which configuration will be the best.

I would suggest you get a pair of routers that can handle multiple leased circuits and use multilink-ppp to bond the 5 circuits together. Have your provider just connect their leased circuits into your routers with 5 the DSU/CSU.

Dear,
Thanks for your suggestion which is excellent, but the problem is that local provider only providing leased lines on Ethernet interface so that we are unable to use this option for multilinking. please advise some other possible solution.

Can you find another local ISP? Where are you located. I know AT&T can provide Internet connections to just about any place, if not all places, in the US and I am sure that Verizon Business can also. I am sure there are others and both AT&T and Verzion Buisness can not only multiple leased lines bonded, they can also provide speeds faster than 2 Mbps.
I am assuming you are in the US because you profile shows that you are in the US Pacific time zone. If you are located outside of the US, my apologizes.
If the only solution is multiple Ethernet hand offs, then most likely each Ethernet hand off will have a unique IP address, which means multiple routers.
With multiple routes you really can't bond them together. You can still get a Cisco router with mulitple Ethernet interfaces and then do load balancing based on:
http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080094820.shtml
There are other devices/routers that do the same thing as this. The biggest problem will be that your ISP must do the same thing (load blance traffic across the 5 routes to you) on their side. Otherwise all of your inbound traffic will come across one of the 5 links.

Dear, Thank you very much for your efforts you are making for me... first of all my apology to have wrong profile. Intact i am located in Bahrain which is GMT+3.
My Senior is bit different here. Only single company "Bahrain Telecom" have infrastructure here which all ISP used for end user services. I am also working for an ISP. My ISP have only one office to provide service in country using coper infrastructure of Bahrain Telecom. Now we got an opportunity to have an other location for office which is near by users. To extend Bandwidth from my Main office to Branch office i need to combine multiple leased lines(From Bahrain Telecom) to provide service to end user.
Now in my Head office we have 4706 Switch that can be used as switch or router and at branch i was planing 2950 as ether channel. i will have full control on both equipment to configure any thing. please guide for best. and also 2950 only support ISL as trunk.

No problem on the timezone, I realize that not everybody updates their profiles, that's why I mentioned it.
I don't think you will be able to use any type of EtherChannel or ISL linking. Both are typically used to connect multiple ports from two devices to give more bandwidth than a single port can handle.
I am assuming that since the ISP is giving you five 2 Mbps links with Ethernet that it is 5 different devices (routers?) with 1 phone circut and 1 Ethernet port on each device has its own IP address. Is this right?

ISP is giving us five 2 Mbps links with Ethernet that it is 5 different devices (routers?) with 1 phone circut and 1 Ethernet port on each device. phone circut is pointing towards ISP side and Ethernet towards our office. same setup will be on branch office but no ip is on Ethernet interfaces. ip we will be managing on our routers/Switches point to point between both site.
