Hello everyone,

I have a Huawei CX600-X8 router, and want to interconnect with a Juniper router.

How do I set MTU value?

Please help me, thank you!

Hi, Qazik.

Huawei, Cisco, and Ericsson (Redback) devices use the IP MTU as the MTU on their Ethernet ports, and other vendors use the Layer 2 MTU (IP MTU + Layer 2 header or CRC). The following table lists the MTUs of common product models.
