Abstract
One embodiment can provide a method and system for synchronizing MTU in a WAN edge with router redundancy. During operation, the system may determine a set of interfaces associated with a network device among a plurality of network devices coupled via inter-switch links. The system can determine a set of layer-3 MTU values corresponding to the set of network interfaces and can determine a highest layer-3 MTU value based on the set of determined layer-3 MTU values. The system can synchronize, via the inter-switch links, the highest layer-3 MTU value, resulting in a set of highest layer-3 MTU values at the network device. The system can determine, based on the set of highest layer-3 MTU values, a global highest layer-3 MTU value. The system can derive a layer-2 MTU value based on the global highest layer-3 MTU value and can configure a respective inter-switch link with the layer-2 MTU value.
