Resolved Caveats—Cisco IOS Release 12.0(32)S8
• CSCek70840
Symptoms: If a multilink interface has one end connected to Cisco 12000 router and the other end
connected to a non-Cisco-12000 router, then the multilink interface receiver, at the non-Cisco-12000
router side, may drop all received packets due to packet fragment loss or out-of-order.
Condition: This may happen immediately when the first member link comes back up again after all
member links of the multilink interface have gone down.
Workaround: 1> Create a new multilink interface.
2> Move the member links from the current multilink interface to the new multilink interface.
