N7K FIB Entry Miss-programmed into wrong SPL Bank - <key>CSCup96876</key>
Hi Guys, We are hitting this bug - (F2E (F2e) with M1 - 32XL proxy layer 3) this is following on from ISSU, Ruvin from Cisco TAC determined this. I have a question, since this is from an ISSU upgrade and the bugID work around recommends:reload the affected line card - will this completely get rid of the bug, we are thinking of reloading the N7K's which should take it out of an ISSU &quot;state&quot;. Tnx Bilal - CCIE #45032
