VRF Implementation on Ethernet port on SRU

Publication Date:  2013-11-23 Views:  116 Downloads:  0
Issue Description
Suddenly traffic stopped to go through Internal traffic to external,this was tested by traceroute tool. 

traceroute show <1ms for traceroute
ping shows <1ms to reach every destination

strange was ping can reach <1ms www.google.com

When disconnect a PC on External side Internal network can still ping destination.
Alarm Information
None
Handling Process
When I test every basic configuration and the problem persist, the idea was put Electrical transceiver to receive traffic instead of SRU RJ45 port.

When use electrical transceiver on LPU the traffic was restablish completly.
Root Cause
First I thing i was problem for DPI system (IPS, and FW).
The analysis start on IPS (USG5360) verifying the configuration and alarms.
Restore the backup configuration until the equipment was working fine but nothing rare.
The decision was to verify first one by one equipment until only NE40 keeps alone to Cisco devices.

Suggestions
Not use RJ45 on SRU port for traffic although it looks like support the same feautures as normal port.
