Description (partial)

- MPLS is being processed by the CPU instead of HW switching.
- <CmdBold>rem com sw show mls vlan-ram<noCmdBold> shows "0" value under vpn-num and netdr shows that mpls is being processed by the CPU:

7600# rem comm sw sh mls vlan-ram 1906 1906

Key: * => Set, - => Clear

vlan eom nf-vpn mpls mc-base siteid stats rpf vpn-num bgp-grp l2-metro rpf-pbr-ovr
1906  *    -     *      0       0     -    -       0      0       -         *      <<<=== vpn-num 0

- There is a possibility of a high CPU due to interrupts.

The symptom may occur on the Cisco 7600 Series Routers after an SSO or module reload is performed on PE with L2VPN in PFC VLAN mode.
