Protocols supported by 4g sim card router

The four most common routing protocols are RIP, IGRP, OSPF, and EIGRP.

RIP(Routing Information Protocols), the most widely used distance vector protocol, was developed by Xerox in the 1970s. At that time, RIP was part of the XNS(Xerox Network Service) protocol cluster. The TCP/IP RIP is an improved version of the xerox protocol. The most important feature of RIP is that it is very simple in both implementation principle and configuration method. RIP calculates routing based on hops and regularly sends update messages to neighbors’ industrial-grade LTE routers.

OSPF protocol was developed in the late 1980s and became an industry standard in the early 1990s. It is a typical link-state protocol. The main features of OSPF include support for VLSM(variable length subnet mask), fast convergence, low bandwidth utilization and so on. OSPF protocol exchanges link-state information between neighbors so that the industrial 4G router can establish a link-state database (LSD). Then, according to the information in the database, the industrial-grade 4G router calculates the routing table of industrial-grade full-network router by using SPF(Shortest Path First) algorithm. The Path selection is mainly based on the bandwidth.

E-Lins’ 4g sim card routers support:
Zebra: Zebra is an IP routing manager.
OSPF: Open Shortest Path First.
OSPF6: Open Shortest Path First for IPv6.
RIP: Routing Information Protocol.
RIPng: it is an IPv6 reincarnation of the RIP protocol.
BGP: Border Gateway Protocol.
