Hi all,
I have a lab, 2 router cisco on GNS3 0.8.6 ( cisco 3725 )

Router 1 f0/0-1 connect f0/0-1 Router 2, i configure channel-group on 2 interface, but when i ping from router 1 to router 2 can not. Can all help me!!!

On router 1:
interface port-channel 1
ip add 192.168.1.1 /24
int ran f0/0 - 1
channel-group 1
no shut

Same on router 2
interface port-channel 1
ip add 192.168.1.1 /24
int ran f0/0 - 1
channel-group 1
no shut
R1#show ip int brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES unset up up
FastEthernet0/1 unassigned YES unset up up
Port-channel1 192.168.1.1 YES manual up up

R2#show ip int brief
Interface IP-Address OK? Method Status Protocol
FastEthernet0/0 unassigned YES unset up up
FastEthernet0/1 unassigned YES unset up up
Port-channel1 192.168.1.2 YES manual up up

I don't think you can do port channel on 2 different router devices.

What you can do is create a L3 port-channel on one router and bind the 2 L3 interfaces to that port-channel, but it seems it needs to connect to a L3 switch.

#Sample config on the router:

interface Port-channel1
ip address20.0.0.1255.255.255.0 load-interval 30
!hold-queue 150in
interface GigabitEthernet0/0 no ip address
load-interval 30
duplex auto
speed auto channel-group 1
in!terface GigabitEthernet0/1 no ip address
load-interval 30
duplex auto
speed auto channel-group 1

Or you can use the configs used on this link:

1. With 3725, it is not possible to have working portchannel with ROUTED interfaces. BUT it is possible to have it working with L2 interfaces (NM-16ESW):

And it works.
2. It is possible to have Port-Channel with routed interfaces connected, but you have to use 7200 router (also, please notice that I have tested that feature with IOS 15.x), I used PA-2FE-TX card in slot 1.
