We noticed this as well on a couple of our M7i running 9.x series code, but not on others running 10.x. This is being caused by a particular prefix (212.118.142.0/24):
rpd[5239]: xx.xx.253.192 (Internal AS xx) Received BAD update for family inet-unicast(1), prefix 212.118.142.0/24 The easy solution is to simply filter out the offending prefix. There are many ways this can be done, but the following did the trick for us: policy-options { prefix-list bad-prefixes { 212.118.142.0/24; } policy-statement BGP-Import { term block-bad-prefixes { from { prefix-list bad-prefixes; } then reject; } } Apply something like this to your BGP import and/or export policy as appropriate and you should be fine.
