Eventually during the ISSU process, the line card software needs to be upgraded. During that part, each line card goes offline one at a time. If you have multiple line cards, design your network such that redundant network paths are connected across different cards to prevent a total outage when each line card is upgraded one-by-one. _______________________________________________ juniper-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/juniper-nsp
