Abstract
Certain embodiments disclosed herein relate to method for egress maximum transmission unit (MTU) enforcement. The method may include receiving a protocol packet at an ingress interface of a network device; make a first determination of a protocol packet payload length; performing an ingress MTU identifier lookup in an ingress MTU identifier table using the protocol packet payload length to obtain an ingress MTU identifier; performing a packet propagation lookup to obtain an egress MTU identifier; performing an MTU enforcement lookup in an MTU enforcement table using the ingress MTU identifier and the egress MTU identifier to obtain an egress action; and performing the egress action.
