, Unlike IPv4, because intermediate nodes cannot fragment IPv6 fragments, it is essential that the source node either send a packet that is the same as or smaller than the maximum transmission unit (MTU) size for the network path or break packets into fragments that are the same size or smaller than the MTU size for the path
Resources cannot be reached over Site-to-Site VPN you can drill down into each sa by issuing: show security ipsec security-association index . The maximum transmission unit (MTU) is the maximum size IP frame the switch can receive for Layer 2 frames inbound on a port Another useful command is the following: Switch# show system mtu System MTU size is 1546 bytes System Jumbo MTU size is 9000 bytes Here you can see that the jumbo MTU size has been configured to 9000 bytes .

As it has been a relatively difficult, and somewhat lengthy, process to increase the path MTU of high-performance national research and education networks from 1500 bytes to 9000 bytes or so, a subsequent increase About Mtu Jumbo Frames Size 3 frame with 3 MPLS Headers looks like (in data filed encapsulating a TCP/P frame): Juniper Networks routers actually maintain multiple routing tables .

In other words, if MPLS MTU is explicitly configured, Junos OS interprets is as total L3 payload size, equaling to the IP payload size plus the total size of MPLS label space being stacked on top of the IP packet Sep 16, 2021 ยท RE: Juniper SRX 1500 Maximum MTU 0/31; The above will only set Ethernet MTU and it is a safe value to use in most cases . The IP MTU and Ethernet maximum frame size are configured separately Maximum transmission unit (MTU) is a well-known parameter in the TCP/IP Networking world .
The L2 MTU does not include the Ethernet header and trailer

(Allowed values are 256 bytes - 9216 bytes)1 LABEL STACKED -> 1488 (MPLS MTU configured manually) - 4 (MPLS label size *1) - 20 (IP overhead) - 8 (ICMP header) = 1456 bytes 2 LABELS STACKED -> 1488 (MPLS MTU configured manually) - 8 (MPLS label size *2) - 20 (IP overhead) - 8 (ICMP header) = 1452 bytesPinging with a size of 1472 and the do-not-fragment on the Juniper side will verify that the path from source to destination has an MTU of 1500 bytes (1472 payload + 8 ICMP header + 20 bytes IP header) Hi Paul, Within the scope of the CCIE Lab Exam, it may be acceptable to issue either of these commands to solve a specific lab task .
