ZXR10 ZSR V2 Series Router Product Description
Under this circumstance, the spanning tree protocol (STP) is generated. As a L2
management protocol, the STP eliminates the L2 loop by blocking redundant links
optionally. At the same time, it is capable of link backup. The same as other
protocols, the STP keeps developing. However, it was initially used as IEEE
802.1D-1998 STP, then generates IEEE 802.1w RSTP(Rapid Spanning Tree
Protocol) and IEEE 802.1s MSTP(Multiple Spanning Tree Protocol).
ZXR10 ZSR V2 supports STP, RSTP and MSTP, and supports transparent
transmission of the above protocols.

MPLS

3.4.1

LDP

MPLS is a multiple layer switching technology. It combines L2 switching and L3 routing,
uses label to aggregate the messages need forwarding. It works in route layer structure,
supporting multiple upper layer protocols. It can be implemented on multiple physical
platforms.
ZXR10 ZSR V2 supports multi-protocol label switching by supporting the following
functions:

It supports basic functions and label forwarding services of MPLS. It
implements LDP signaling protocol, which takes charge of label distribution,
LSP establishment, and parameters needed in LSP establishment.

It supports Graceful Restart at MPLS signaling protocol layer. It can keep label
data forwarding when protocol is interrupted.

It supports MPLS Ping/Tracert. It uses MPLS echo request and MPLS echo
reply to check the availability of LSP.

It supports LDP FRR. It can takes quick switching of data flow when LSP
interrupts.

It supports MPLS LSP load balancing.

It supports multiple layer label processing.

It supports LSP loop check mechanism.
