Abstract
In one embodiment, when a packet is received at a device in a network, the device may determine whether a time-to-live (TTL) value of the packet has expired. If the TTL value has not expired, the device forwards the packet to a next-hop device in the network. If the TTL value has expired, however, the device dampens a forwarding state related to the packet for an amount of time until resuming the forwarding state after that amount of time has elapsed. In an example embodiment, the packet is received within a multipoint-to-multipoint (MP2MP) bidirectional tunnel.
