Hi Ramesh,
Are the “Policed Discards”, “L3 Incompletes” and DA Rejects increasing all the time? Can you disable all Cisco proprietary protocols such as CDP and keepalives on Cisco port? Clear the interface stats ib fe-0/1/0 and then monitor if these counters are still incrementing.
<...>
Input errors:
Errors: 35391, Drops: 0, Framing errors: 0, Runts: 0, Policed discards: 181893, L3 incompletes: 35391, L2 channel errors: 0, L2 mismatch timeouts: 0,
<...>
<..>
Input DA rejects 217283
<..>
Also, pls check, if possible, the rate at which these counters increments matches the rate at which IPv6 packets are being sent from Cisco. These drops counts matches the multicast packets received on the interface.
Multicast packets 223208 210418
Did you try to run tcpdump on the interface to see if you are receiving any OSPFv3 packets from Cisco?
Also, any firewall filter applied to either fe-, ge- or lo0 interface?
Thanks,
Nilesh

Ramesh,
Do you see cisco neighbor in "show ipv6 neighbors"?
Thanks,
