in which case router drops the packet with too large MTU

m4rtin

As I understand, in case router interface receives an IPv4 packet(for example telnet traffic) larger than the interface MTU, it has to drop the packet? And in case the router interface MTU is larger than the received packet, but the next-hop MTU is smaller than the received packet, then router can either:1) drop packet and send ICMP notification to packet source2) fragment the packet and forward it in multiple parts towards the next-hopAm I correct?

The router will attempt to fragment the packet as long as the DF bit is not set to 1.
