Per discussed over phone, the build-in TenGigE0/0/2/2 and 0/0/2/3 on ASR9001 sometimes changes state to down/down, the workaround solution to remedy the issue is shut/no shut the both interfaces. As you mentioned the issue recur on morning today, to checking and investigating the issue then kindly share the syslog / error log and MRTG graph to me krub. Thanks in advance.
