Cisco Bug: CSCta57834 - MA: when v6 link local addr changes, send change NFN, not delete/add
Jun 08, 2018
- Cisco Carrier Routing System
Known Affected Releases
Symptom: After changing the IPv6 link local on an interface over which we're peering with isis or ospfv3, we see 6-8 seconds of traffic loss. Conditions: Currently two messages are sent when we change the LL address, a delete, and an add. IGPs react to the delete by tearing down the session (then rebuilding when the add is received). When we send a single change notification, this will no longer be necessary.
