Hi group,
I know 802.3ad has nothing to do with FastEtherChannel but as
Stephane LITKOWSKI suggested it several days ago, if we force
the channel on the cisco : It works fine ...
------ fe-0/2/2 7/3 ---------
| |---------------------------| 6509 |
| | fe-0/2/1 7/2 | |
| M5 |---------------------------| + |
| | fe-0/2/0 7/1 | |
| |---------------------------| MSFC |
------ ---------
I noticed several points :
- if you have only one link up, the ae0 is down
- but if you only deconnect one interface, the aggregate link
is still working (with just 2 fastEthernet)
On the juniper I just configure the ae0 interface with the
IP add : 10.1.1.1/24
and on the Cisco box, the VLAN 100 with IP : 10.1.1.2/24
Check the config :

If you're interested, we also did the test with Juniper and Extreme Summit
(802.3ad at both side).
