I have just added a 450g2 to my environment. Ideally, i'd have more than 1 fiber strand going from this idf to the MDF where the 670s reside. Those 670's run vrrp. Each fiber uplink would go to an interface on one of the 670s. Right now, i only have 1 spare fiber strand, so i only have the switch connected to one of the 670s, can i go ahead and setup mlag on the new switch and then configure whatever else i need on the 670s?, or should i wait until i have another fiber strand available to be able to have 2 uplinks, one to each 670?
It seems that when i setup mlag on the 670s, i can no longer ping or ssh into the new 450-g2 but when i delete the mlag and group sharing interface, then it all works again.
