this can be caused by routing loops which happen because the RIB gets out of date with respect to the rest of the network. This will result in lots of icmp ttl-expired packets to be generated by the RP, which will cause IP Input to get excited. Try configuring the following: mls rate-limit all ttl-failure <xxx> mls rate-limit all mtu-failure <xxx> mls rate-limit unicast ip icmp redirect <xxx> mls rate-limit unicast ip icmp unreachable <xxx> If you already have lots of other mls rate limiters configured, you may need to be careful when configuring these, because there are more mls rate limiter options than the hardware is capable of supporting at the same time.
