set the keepalive interval to 10 seconds or greater.
PPP requires three keepalives to fail before it brings down the session. Thirty seconds
(10 seconds x three) provides a safe margin to maintain PPP sessions in case of
any traffic loss during the unified ISSU operation.
This example shows the at-0/0/1 interface only.
