Description (partial)

Bundle-Ethernet interface used as an L3 Ethernet Segment in EVPN remains in LACP OOS state after being removed from evpn configuration.

This affects all platforms that support EVPN in the 7.0.90 release: ASR9k and NCS5500.
The issue requires the user to have configured both the staggered bringup timer (via <CmdBold>staggered-bringup-timer<noCmdBold>) and cost out (via <CmdBold>cost-out<noCmdBold>) under the evpn submode.
The issue requires the user to perform the following steps:
- Remove <CmdBold>cost-out<noCmdBold> configuration
- Without waiting for the staggered bringup to complete, remove the L3 Bundle from the evpn submode.
