Description

In a Next Generation MVPN scenario, a kernel memory buffer may get corrupted when the router receives a bootstrap or auto-RP message whose packet size exceeds 204 bytes. The memory corruption will cause the Junos kernel to crash every time such a packet is received. This problem will only be encountered in a Next-Gen MVPN scenarios that use Ingress Replication as the P-tunnel type and has Auto-RP or Bootstrap as the group-to-RP mapping mechanism.
