combine two frame connections?

[shoaff]

I am looking to combine two 512k Frame Relay connections. Is this possible and what type of FR router is needed? <br><br>I have done this in the past using Multi-Link w/ PPP but I am new w/ Frame Relay.<br><br>Thanks in Advance,<br><br>Mike<br><br>

Are these frame-relays at the same site ? What is your application goin to be ?

I have a point to point wireless frame relay connection that can only handle 512k. I would like to add another point to point and combine them on both ends. <br><br>How it is structured now is that on point (A) I have a Cisco 1005 connected to a wireless modem and on side (B) I have another wireless modem connected to a Cisco 1005. I would like to find a Router that has multiple ports and would be able to combine the bandwidth.&nbsp;&nbsp;

I know only the work around use load balancing Routing alogriths like OSPF and assign both the PVC equal cost

Static routes allow you to set up load balancing after a fashion. Keep in mind that the IOS load balances across routes first and not interfaces. The easiest way to configure multiple routes on the same interface is to use the secondary IP command

Router 1
!
interface serial 0
ip address 192.0.0.1 255.255.255.0
ip address 192.0.0.2 255.255.255.0 secondary ! second route on same interface

interface serial 1
ip address 192.1.0.1 255.255.255.0
ip address 192.1.0.2 255.255.255.0 secondary

ip route 200.2.0.0 255.255.255.0 196.0.0.4; goes to serial 0
ip route 200.2.0.0 255.255.255.0 196.0.0.5; goes to serial 0
ip route 200.2.0.0 255.255.255.0 196.1.0.4; goes to serial 1

Router 2
!
interface ethernet 0
ip address 200.2.0.1 255.255.255.0
!
interface serial 0
ip address 196.0.0.4 255.255.255.0
ip address 196.0.0.5 255.255.255.0 secondary
!
interface serial 1
ip address 196.1.0.4 255.255.255.0
ip address 196.1.0.5 255.255.255.0 secondary


The traffic would go out router 1 across the two IPs on serial 0 first then across 1 IP on serial 1
This gives you unequal load balancing.

You may be able to massage this into something you can use.

there are several other options as well. You can set up equal cost load balancing and
or setup ppp multilink. There are some good choices here, take the best one for your
application and run with it. #-) Good Luck !!!

Have any body have tried link aggrigation using PPPOFR. I am not sure it will work or not. Theoratically by doing this you get PPP properties on Frame-Relay. I have only tried normal PPP (w/o link aggrigation)with CISCO IOS 12.0 image only issues was bridging (RFC 1638).

I am still trying to combine 2 Frame Relay connections together. I started working with MultiLink PPP but I do not think you can do this over Frame Relay. When you have to define encapsulation you can only use PPP.
Does anyone have any experience with this?

How my set up looks no is I have on side (A) a Cisco 2501 w/ two serial ports and on side (b) I have a Cisco 2620 with 2 serial ports.
