That's correct but in this case one is LACP (802.3ad) and one is not so it won't bring up the links at all.

Wouldn't that, in conjunction with a JunOS without an "lacp" stanza under the ifd / interface stanza (lacp passive) work just fine? I've mostly only been doing JunOS-JunOS LACP lately, though I've done it quite a bit with Cisco-Cisco in the past. LACP is worth running on your links if it works, IMO. Maybe try setting active on the JunOS and Cisco sides? ! interface Fa1/0/9 channel-group 10 mode active ! set interface ae1 aggregated-ether-options lacp active _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
